Yet in the prior art, the method that is used for the radiance of definite wireless device has a lot of shortcomings.Some determine that the test of radiance relates to the destructiveness change to wireless device.For example, in an example, the signal path between antenna and the receiver is interrupted, and is re-routed to external radio frequency (" RF ") connector.Then, carry out the radiation signal power measurement, thereby this external test facility has replaced the receiver on this wireless device by external test facility at this connector place interface.The existence of external RF connector and the external cable that is associated may make the actual emanations performance distortion of wireless device.In addition, owing to carry out required optional equipment and the additional manpower of these destructive changes, these changes have also increased the expense of test process.In addition, destructive change has also increased extra-pay owing to making the wireless device that is modified can't be used for other test.
In addition, in a wireless communication system, may be from the RF modulation signal of transmitter via many travel paths arrival receivers.Usually, the characteristic of travel path can be because for example decline and multiple factor such as multipath and variation in time.
In addition, buildings (for example house) and the surrounding terrain that comprises wall and hillside caused scattering and the reflection that is transmitted.Scattering that transmits and reflection have caused the many signal path from transmitted from transmitter to receiver.The forming factors of many signal path changes along with moving of receiver.
Other signal source has also caused the deterioration of desired signal.Other signal source may be the transmitter that produces spur signal wittingly in other transmitter that moves on the frequency identical with desired signal and the frequency band at desired signal.In addition, the deterioration of other signal source also may produce in receiver self.The grade that signal amplifier in the receiver and signal Processing level may reduce desired signal with respect to thermal noise level.Signal amplifier and processor in the receiver also may produce noise component, perhaps make the distorted signals that is received and further reduce its quality.
For the diversity that resists harmful path effects being provided and improving performance, can use a plurality of antennas that transmit and receive.If the travel path that transmits and receives between the antenna is linear independently (promptly, transmission on one paths is not to form by the linear junction of the transmission on other path is incompatible), in general this situation takes place in a certain scope to I haven't seen you for ages, and the possibility that then correctly receives data transmission increases along with the increase of antenna amount.Therefore, in general, along with the increase that transmits and receives antenna amount, diversity is increased and performance is promoted.
In addition, wireless device may be because multiple former thereby use a plurality of antennas.For example, wireless device often need be operated on a plurality of frequency bands and serve a plurality of operator schemes.Another reason is at present the advanced transmitter framework to be embodied as the performance of using a plurality of antennas to improve some pattern in above-mentioned a plurality of pattern.When operating at the same time, these patterns may interfere with each other, thereby cause the reduction of overall performance.Therefore, be necessary to design the accurate device of the radiance that can estimate wireless device, it can catch the self-interference effect.Current approach need be estimated knockdown device/Antenna Design with some steps, and the test accuracy of current utilization " wired " test exists uncertain.Therefore, also must exploitation design reliably and method of testing.

In other embodiments, for example, predetermined radiance test 24 can comprise relating to and is derived from test wireless device and radio wave signal 46 that be launched into radio-signal system 32.This test is the performance test of the emission chain/antenna of wireless device 12.In the embodiment of the base station of radio-signal system 32 analog cellular telephone networks, the radio wave signal 46 that is derived from wireless device can be considered reverse channel signals.Signal 46 comprises reference signal characteristics 48, and it can be used as the benchmark of subsequent calculations, and radio-signal system 32 reception and processing signals 46, generates the corresponding measuring-signal feature 50 that is received by system 32 thus.In this embodiment, the test and management module on the controller system 14 44 is carried out the relevant position recording of information to measuring-signal feature 50 and discovery in the component 26 of location.Then, system 10 is at the enterprising line ordering in remaining a plurality of precalculated positions, till all receiving signal 46 in all positions of being determined by given predetermined radiance test 24.In case all detecting informations all are recorded, the relevant position information (it also can be considered synchronizing information 36) that test and management module 44 is just analyzed all measuring-signal features that are recorded 50 and come self-align component 26, and the radiance feature 42 of generation wireless device 12.In this case, for example, radiance feature 42 can comprise the measured value of the transmission performance of wireless device 12, gains as emissive power.In addition, if with a plurality of precalculated positions that each test is associated in exist overlappingly, then wireless device 12 can be set to simultaneously received signal 18 and transmit 46, shortens the test duration thus.
Therefore, system 10 is included in direct recorder machine data on the wireless device 12 with having superiority, has eliminated the demand to aerial lug and cable thus, and wherein aerial lug and cable may make the true receiver coherent radiation performance distortion of device.In addition, system 10 provides measuring-signal feature 38 and positional information or corresponding to the wireless synchronization of the physical coordinates of each selected location 22 with having superiority, has eliminated thus the aerial lug that is connected to external sync and equipment for after-treatment and the demand of cable.Carry out when in addition, record that is provided by the wireless device 12 of system 10 and synchronizing function allow a plurality of radiances test.Therefore, system 10 provides the high-efficient disposition of the radiance that is used for definite wireless device 12.

In this particular example, for example, in the far field anechoic room that is calibrated, carry out and measure.Test application is written into test telephone, and the control of other special use and the poster processing soft are written into the principal computer of control chamber (chamber) equipment.With the cell site simulator or call out the electromagnetic horn that box (call box) is connected to chamber, realize that thus the air download (OTA) of the test telephone on the rotating basis that is installed in the chamber far-end is called out.
For the receiving mode test, order this phone that user-defined packet is recorded on the storer of test telephone.Defined packet (for example " rake refers to channel estimating " daily record grouping) comprises multiple pilot signal (for example same-phase and quadrature phase), and described multiple pilot signal is to be received by telephone antenna when the electromagnetic plane wave irradiation that phone is launched from the calling cartridge device.Can be by coming trigger recording to the order of test telephone wireless transmission from calling out box.By moving of this recording events and pedestal and test telephone is synchronous, each place of taking measurement of an angle on the visual field that covers sphere obtains multiple same-phase and quadrature phase receives pattern data.In addition, utilize the chamber loudspeaker that carry out vertical and horizontal polarization orientation to test, receive pattern thereby obtain vertical and horizontal.In addition, for the phone of enabling diversity, by writing down the multiple connection receipts pattern that identical integrated data obtains secondary antenna in a similar fashion.
Test for emission mode, power meter is used for measuring by test telephone utilizes the radiation power of telephony transmitter with maximum power transmission at given direction of measurement.For example via carrying out radiation with its maximum transmission power from the OTA signal command test telephone of calling out cartridge device.Institute's emitted power is collected by the chamber loudspeaker, and is taken measurement of an angle with each by power meter and to measure.In addition, determine chamber path loss, it can be produced by reference signal, can determine the EIRP of phone thus.When test telephone being rotated to each test angle that covers sphere, store measured data in real time.In addition, test, obtain vertical and horizontal polarization EIRP pattern thus for the chamber loudspeaker that carry out vertical and horizontal polarization location.
Take measurement of an angle with each and sequentially to carry out whole three measurements, that is, the emission EIRP and the secondary antenna of advocating peace receive multiple field measurement.Therefore, can utilize the execution of single test to collect whole receptions and emission data.

In relating to the embodiment of local analytics (square frame 190), this method also comprises the record (square frame 192) that receives measurement features and synchrodata from wireless device.For example, radiation test manager module 44 is from wireless device 12 receiving trap test logs 86.If the daily record that is received comprises the measuring-signal feature synchronous with positional information (square frame 194), then this method also comprises based on pre-setting analysis agreement and analyzes the daily record (square frame 196) that is received, and generates radiance feature (square frame 198).For example, performance analyser module 130 can utilize analysis agreement 90 to come analytical equipment test log 86, so that determine radiance feature 42.Alternatively, if the daily record that is received not synchronously (square frame 194), then this method comprises that log information and the local log information that will be received are synchronous, with generation synchrodata daily record (square frame 200).For example, performance analyser module 130 can be carried out synchronous logic 132, by mating the synchronizing information that comprises in each daily record device to test daily record 86 and control test log 122 are made up.In this case, in case generated synchrodata daily record 134, this method just can continue to analyze synchronizing information (square frame 196) via pre-setting analysis agreement, and generates radiance feature 42 (square frames 198).
Alternatively, in the embodiment that relates to the remote analysis analysis of wireless device 12 (for example to) (square frame 190), this method can comprise the analysis agreement (square frame 198) that is associated with predetermined radiation test to another device emission.For example, if be not included as the part of device to test configuration 76, then radiation test manager module 44 can for example be passed through signal 18 to wireless device 12 emission analysis agreements 90.Alternatively, this embodiment of this method can also comprise from another device received radiation performance characteristic (square frame 200).For example, if wireless device comprises analyzer module 88, then radiation test manager module 44 can be from wireless device 12 received radiation performance characteristics.
Especially, in a limiting examples of describing emphatically before, described embodiment can be used to cell phone radiating antenna/receiver test, for example: (1) total omnidirectional sensitivity (TIS) test; (2) total radiant power (TRP) test; And (3) antenna ra-diation pattern correlativity (rho) test.
These three radiation tests all need carry out sphere to antenna gain at the vertical and horizontal polarization and measure.Institute has plenty of the measurement to antenna receiving gain pattern admittedly in the TIS test, although and it is traditionally via receiver sensitivity realization indirectly.The measurement to the antenna transmitting gain is depended in the TRP test.Test of antenna pattern correlativity or antenna rho test need receive (" RX ") gain (comprising amplitude and phase place) and measure simultaneously to the complex voltage of two or more antennas.For all tests, the physical process of measuring the sphere gain is basic identical: when phone physically rotates around sphere (it is usually with a series of great circle cutting (elevation cut)), and the loss between measurand transmitter and the receiver.Difference between each test is the characteristic and the position of transmitter and receiver.
Under the situation of TIS test and the test of antenna ra-diation pattern correlativity, transmitter (being generally the cell site simulator as communication simulation device module 142) is connected to scope directional antenna (for example electromagnetic horn 144), and receiver is connected to tested antenna.In this case, receiver is a receiver module 70, and tested antenna is the antenna system 72 of wireless device 12.For the TRP test, wireless device 12 serves as transmitter, and receiver is the RF power meter 148 that is connected to scope antenna 144.
In these tests, necessary measurement is carried out in 70 pairs of tests based on RX of the receiver module of wireless device 12 (RX gain, antenna Rho).By using the receiver module 70 of wireless device 12, described embodiment provides a plurality of advantages, and for example: save time, this is because needn't change wireless device 12 for test; And, potentially, more accurate result, this be because in the prior art to may change the gain pattern of antenna in the change of wireless device 12 and the prior art to the use of external unit and cable.
In addition, radiance test module 40 provides receiving the visit of machine data 82, and described receiver data are for example estimated from RX AGC (received power) and the pilot tone I/Q that each rake rake refers to via the API 62 with processing subsystem 64 interfaces.In addition, radiance test module 40 is recorded in receiver data 82 in the device to test daily record 74 in the data storage bank 58.This method provides can not use cable to connect the advantage of just testing wireless device 12.Therefore, wireless device 12 had both become testing apparatus and had also become data recorder.Provide thus with more representative state (no cable connects) and estimated the interference test setting still less of wireless device 12, and can save time.
In addition, above-mentioned setting can all be recorded in single position with all test datas that needs, that is, be recorded in the wireless device 12.For example, by system 10, can be to positioner 136 inquiring position information when each power measurement.At test period, transmit (not using cable) to wireless device 12 with this positional information or corresponding to some data (for example time) of this positional information, therefore, all test datas that needs all can be recorded on the wireless device 12.Make thus wireless device 12 can with receiver parameters record position information synchronously, thereby can collect the record of power vs. position in real time.Alternatively, controller system 14 can record position information and time, perhaps corresponding to positional information can be synchronous with wireless device 12 other variable.Simultaneously, wireless device measured data parameters and the time (or other synchrodata) of 12 records.Alternatively, wireless device 12 can send daily records to controller system 14, and controller system 14 can be synchronous with positional information and measured data parameters via time or other synchrodata.For example, can be via following parameter with positional information or be that synchrodata 36 is transmitted into wireless device 12: the data socket of opening on active traffic channel at least, its one or more use in the field in forward link overhead channel message is encoded, for example the latitude and longitude of base station in SID, network identity (" NID ") or the system parameters message; And data can be in for example bluetooth

Or transmit on the auxiliary channel of 802.11 channels.
The TIS test has solved the reciprocation of antenna and phone electron device, comprises from the blocking effect of not expecting the noise generation of the phone electron device institute radiation that can be couple to Anneta module.Especially, for the TIS test, the cdma receiver sensitivity measure need be found the service channel power (particularly, frame error rate (FER) becomes 0.5% point) that received signal quality begins to worsen.Yet, should be pointed out that according to given situation, can specify other FER threshold value.In addition, should be pointed out that also and can use other threshold parameter.For example, by using global system for mobile communications (" GSM ") technology, threshold parameter can be bit error rate (" BER ").Yet, for the situation of CDMA, Feng Wotongxin ﹠amp; The process regulation that is used for the TIS test of internet society (" CTIA ") appointment: at Theta (elevation angle) and Phi (position angle) axle, per 30 ° are just carried out a radiosensitivity measurement.In addition, depend on this situation, can use other precalculated position.Except the point Theta=0 ° and 180 °, this prior art needs 60 independent sensitivity measures for each polarization, and described sensitivity measure is then in the sphere upper integral, thereby produces TIS tolerance.This test execution is got up very time-consuming, and this is because the identification of the sensitivity point of each position all needs a progressive iterative process, and this all manually carries out in the past.
Yet described embodiment can accelerate the execution speed of TIS test.Radiosensitivity around sphere only changes along with the variation of antenna RX gain.All other factorses in the link all are constant.This shows that if the RX gain pattern of antenna is known, then (preferably, maximum antenna gain point) need carry out sensitivity measure only at single reference point place.Therefore, any other point on sphere (θ, the radiosensitivity Sens that φ) locates can be expressed as:
Sens(θ,φ)=Sens(θ 0,φ 0)+[G RX(θ,φ)-G RX0,φ 0)] (1)
Wherein, (θ is that spherical co-ordinate (θ, represent with dBm, G by the radiosensitivity of φ) locating φ) to Sens RX(θ is that (θ, the RX antenna gain of φ) locating is represented with dB, and (θ in spherical co-ordinate φ) 0, φ 0) be the coordinate of reference sensitivity measured value, that is, be preferably sensitivity in the maximum gain position.
In the prior art, this method is unpractical, and this is because as previously mentioned, in the prior art in order to measure G RX(θ φ) has carried out change devastatingly to device.Yet described embodiment can determine to non-destructive G RX(θ, φ), this is because the received power measurement is to be carried out by the receiver module 70 of wireless device 12.Therefore, In a particular embodiment, can use following fast method for each polarization (vertical and horizontal):
(1) carries out radiance test module 40 in predetermined a plurality of positions to measure and record G RX(θ, φ), for example for (θ φ) increases progressively with 30 °, and it has defined spherical shape (except θ=0 ° and 180 °) in this case;
Position (θ when (2) identification GRX is maximal value 0, φ 0);
(3) at position (θ 0, φ 0) locate to carry out the test of single radiosensitivity, that is, in monitoring FER (being BER perhaps), reduce emissive power to wireless device so that determine Sens (θ for device based on GSM 0, φ 0), till arriving predetermined threshold FER;
(4) above-mentioned equation 1 is applied to whole precalculated position set (for example aforesaid sphere position), so as at each precalculated position determine Sens (θ, φ); And
(5) the precalculated position (θ φ) carries out integration, so that determine the TIS tolerance of wireless device to the Sens that calculated in shape.
In other words, TIS needs " radiosensitivity pattern " EIS v(θ, φ) and EIS h(θ, φ), wherein, EIS V or h(effectively omnidirectional sensibility) is in given taking measurement of an angle (θ, the radiation receiver sensitivity of φ) locating for given BER or FER threshold value.Yet in test cabinet, these values are difficult to directly measure, and this is because call out often go offline (for example, received signal level may be reduced under the phone noise level) when test telephone is rotated to antenna ra-diation pattern for null value.For fear of this problem,, utilize measured peak sensitivity value to carry out convergent-divergent to derive EIS then to receiving pattern to be enough to the avoiding received power level of dropped calls to measure the reception pattern v(θ, φ) and EIS h(θ, φ) pattern.For example, in one embodiment, chamber path loss is calibrated, so that known power level is incided on the test telephone, it approximates the background noise of phone greatly or (for example exceeds 30dB, for typical phone, the pact-70dBm at call test point place will be a good numerical value).Yet, should be pointed out that according to given test situation, also can use other dBm value.By being standardized as received signal intensity indication (" RSSI ") value (being measured power), from the pattern data of last planar survey, derive antenna gain pattern (G v(θ, φ), G h(θ, φ)), wherein phone with reference power level (is being-report described RSSI value usually when 70dBm) (via the RF test port on the phone) " injection " is to receiver in this case.If in the given place of taking measurement of an angle antenna gain is that the power incident at 0dBi and phone place is-70dBm that then this value is the value that phone will be reported.Indicated receiving antenna gain with the deviation of this value.
Thereby in anechoic room, (θ φ) and corresponding to chamber loudspeaker polarization (vertical v or horizontal h) measures peak of radiation receiver sensitivity, i.e. Peak EIS (θ with incident angle Pk, φ Pk), produce peak antenna gain thus.By utilizing peak E IS value to come standardization antenna gain pattern, obtain the EIS pattern:
EIS v?or?h(θ,φ)=PeakEIS(θ pk,φ pk?)-G v?or?h(θ,φ)
In case know EIS v(θ, φ) and EIS h(θ, φ) pattern just obtain TIS tolerance by on the test angle sphere pattern being carried out space average:

This technology allows fully on the wireless device 12, calculate in control system 14 places or its combination fully.For example, wireless device 12 can be in the synchrodata 26 that receives positional information for example or for example during the synchrodata 26 of temporal information 114, determines independently in conjunction with the daily record from the synchrodata 26 contrast positional informations of controller system 14.Wireless device 12 can be determined G RX0, φ 0) and to controller system 14 transmitting site (θ 0, φ 0), to be used for being redirected and the startup of the sensitivity test part of agreement of positioning system 28.Then, wireless device 12 can calculate required Sens (θ, φ) and carry out integration, to determine to be stored and/or to send to the TIS tolerance of controller system 14.
Alternatively, can after step 1 and 2, interrupt, so that allow device to test daily record 86 is unloaded to for example controller system 14 from wireless device 12, to determine G by carrying out aftertreatment in the data aggregation at wireless device 12 places RX(θ, φ) and G RX0, φ 0).For example, daily record 86 comprises the record of measurement data contrast synchrodata.At this moment, controller system 14 can transmit control signal 16, so that wireless device is positioned at position (θ 0, φ 0) locate, to carry out the radiosensitivity test.Similarly, wireless device 12 can or determined Sens (θ after having write down one group of sensitivity measure value of maximum gain position 0, φ 0) discharge mechanism test log 86 afterwards.Then, controller system 14 can be used equation 1 and/or carry out integration on sphere in all positions, thereby determines TIS tolerance.
In addition, can be to 12 execution in step 1 of the wireless device in the idle pulley, this is movable because of RX_AGC.Advantageously, this technology has been eliminated the needs of keeping service call duration of test.Yet, should be pointed out that for step 3 wireless device 12 can be in the calling, this is because can be only at business datum frame definition FER.
In one embodiment, above-mentioned sensitivity test is carried out by the artificially---and the emission power of forward link on the manual adjustments cell site simulator is to realize the target FER on the wireless device 12.As mentioned above, described embodiment provides automatic sensitivity test.For example, controller system 14 utilizes wireless device 12 to set up and calls out, and little by little reduces forward link power then, and the record of holding power vs. time in control test log 122 while.Simultaneously, radiance test module 40 with FER vs. time keeping in device to test daily record 86.Radiation test manager module 44 receiving trap test logs 86, and carry out synchronous logic 132, so that measured value was associated with writing time in each daily record 122 and 86, thereby generation comprises the synchronization log 134 of the record of FER vs. power.Based on this record of FER vs. power, performance analyser module 130 can determine that FER is 0.5% point.
In addition, alternatively,, then all data that need can be recorded in wireless device 12 places if on the forward link forward emitting power is delivered to wireless device 12.In this case, radiance test module 40 execution analysis device modules 88 are 0.5% point to determine FER.Therefore, merging record on the wireless device 12 has advantageously eliminated respectively from the needs of the offline synchronization of the daily record 122 of controller system 14 and wireless device 12 and 86.
About TRP, the TRP test is the performance test to the emission chain of wireless device 12.For this test, can dispose 76 via device to test wireless device 12 is configured to launch with total power.For example, in the CDMA device, aforesaid operations sends " all (all-up) " power control bit and keeps service call to realize simultaneously by indicating cell website simulator usually.Measure the power that receives from wireless device 12 by the power meter 148 that is connected to antenna range orientation (loudspeaker) antenna 144.
The process regulation that is used for the TRP test of CTIA appointment: at Theta (elevation angle) and Phi (position angle) axle, for each polarization, per 15 ° are just carried out power measurement one time.Except the point of Theta=0 ° and 180 °, this technology needs 264 independent data points for each polarization, and these points are subsequently in the sphere upper integral, thereby produces TRP tolerance.Because overlapping in the position measured of expectation, described embodiment allows to carry out the TRP test simultaneously with the TIS test, thereby substantial saving of time is provided.
Alternatively, another method that wireless device 12 is configured to carry out full power operation is: gain and come the artificially to set the digital transmission gain by digital transmission is set with factory test mode (FTM).In this configuration, the TRP test can be determined to be performed simultaneously with above idle pulley RX gain about the TIS test description, thereby potential saving of time is provided.
In other words, TRP tolerance can by under establish an equation to determine:
Figure C20058004447800431
Wherein, EIRP v(θ φ) is effective isotropic radiated power for vertical polarization, and EIRP h(θ φ) is effective isotropic radiated power for horizontal polarization, and it can be from transmitting gain pattern G V or h(θ, determine in φ):
G v?or?h(θ,φ)=EIRP v?or?h(θ,φ)/MaxPAOut
Wherein, MaxPAOut is under each test frequency, the output of the peak power of power amplifier, that is, and the output of the peak power of transmitter module 68.
Thus, peak value Effective Radiated Power PeakEIRP is the maximal value of EIRP pattern:
PeakEIRP=Max[Max(EIRP v(θ,φ)),Max(EIRP h(θ,φ))]
The administrative authentication of wireless device (being SAR, category level authentication, Radiation Emission) may need PeakEIRP.
In addition, another emission mode radiance feature is antenna efficiency η:

It is derived to be similar to from the mode of antenna gain pattern derivation TRP.
Pattern envelope correlation ρ eThe possibility of the double antenna in the assessment mobile environment, the diversity gain of double-receiver phone.The rho test is based on the measurement of complex gain being determined the decline correlativity.Can be used to estimate the envelope correlation that last incident field model caused by described antenna for the measured multiple Rx pattern of main antenna and secondary antenna (for example, E θ 1 as described below, E φ 1, E θ 2, E φ 2).
Along with the appearance as the receiver diversity of the feature that can provide in modern transfer table modulator-demodular unit (" MSM ") ASIC, people begin need be used for predicting the radiation test of multiaerial system in the operational effect of field.The MIMO device also will be benefited from this class testing.The important design parameter of double antenna device is the correlativity between the antenna.For receive diversity, the antenna that produces the height correlation signal in the double reception chain has minimum effect.Described embodiment is used as the diversity gain premeasuring in the dual-antenna system with envelope correlation (being also referred to as the decline correlativity).
Can predict envelope correlation according to the right complex voltage gain pattern of antenna and the incident RF field of supposition.As other receiving gain is measured, use wireline test to measure multiple antenna gain pattern traditionally.Under the situation of commercial wireless device, this need change device devastatingly so that aerial lug to be installed.Yet, substituting destructive change, described embodiment uses the element of the receiver module 70 of wireless device 12.For example, under cellular situation, CDMA rake receiver function need be estimated the precise phase of pilot channel.Provide movable pilot channel by cell site simulator from for example simulator 142, and receive the received power (it can be found) of chain/antenna and when phone rotates around sphere, estimate (it can be harrowed index at RX_Pilot and find according in dividing into groups) in the RX_AGC packet by radiance test module 40 is write down from each, can on wireless device 12, generate the complex gain pattern fully from same-phase/quadrature phase (I/Q) pilot tone of rake receiver.This need not mobile phone is carried out the destructiveness change.
As above description at the receiver gain pattern, if during data aggregation, by forward link for example with the position/angles information wireless be transmitted into device, then all records can merge at wireless device 12.
If wireless device 12 is not realized receiver diversity with idle pulley exactly, then can utilize the wireless device 12 that is in the service call to realize that the multiple pattern of many antennas is definite.
Especially, described embodiment comprises following equipment and method, and it is used for estimating the envelope decline correlativity ρ in mobile environment according to from the right measured complex radiation pattern of antenna on the wireless device 12 in the test cabinet 20 e
Owing to have multiple antenna field pattern E m(θ, k electromagnetic plane wave (ray) F φ) m k(θ, φ), with (θ, φ) incide m the complex voltage V on the antenna element can by under establish an equation and provide:

Thereby, total variance E[|V of antenna field pattern again at this antenna element place m k| 2] be:
E [ | V m k | 2 ] = P V · ∫ 0 2 π ∫ 0 π | E θ , m ( θ , φ ) | 2 · P θ ( θ , φ ) · sin θ · dθ · dφ
= P H · ∫ 0 2 π ∫ 0 π | E θ , m ( θ , φ ) | 2 · P θ ( θ , φ ) · sin θ · dθ · dφ
Wherein, P θAnd P φBe illustrated in the incident field angle power density functions in θ (vertical polarization) and φ (horizontal polarization) direction; P VAnd P HFor example can be illustrated respectively in the constant of the dried equal incident power on the wireless device 12 in θ (vertically) and φ (level) polarization by along in the representative RF environment of random drive route discovery.

Wherein, XPR=P V/ P H, and wherein, * indicates complex conjugate.
According to the variance and the cross covariance of two signals, the envelope correlation coefficient can be given:
ρ e ≅ | ρ | 2 = | E [ V 1 k · V 2 k * ] | 2 E [ V 1 k · V 1 k * ] · E [ V 2 k · V 2 k * ]
Can in aforementioned equation, use the multiple antenna pattern E θ 1, E φ 1, E θ 2, the E φ 2 that measure for wireless device 12 to calculate ρ with antenna system 72 (it has the double antenna that adopts walk-off angle on the visual field that covers 4 π sterad) e, as follows:

Wherein: R is relevant with cross covariance between antenna 1 and 2; I, j are the indexes relevant with the angle position of measured sampling; N θ represents the quantity of θ angle; And N φ represents the quantity of φ angle.
Thereby, envelope correlation ρ eFor:
ρ e = | R 12 | 2 σ 1 · σ 2
In these calculate, the value of XPR (polarizability of incident field) and P θAnd P φThe form of function depends on RF environment (for example urban district, countryside, rural area, highway etc.).
As an example, the channel model for having even expansion in the position angle and the Gauss in elevation angle expansion can provide P θAnd P φFollowing expression:
Pθi = P v i = A V · exp - [ ( θi - m V ) 2 2 · σ V 2 ] Pφi = P h i = A h · exp - [ ( θi - m h ) 2 2 · σ h 2 ]

Yet, should be pointed out that also and can use other expression.
Some phone model have been produced with double antenna.Multiple pattern is measured, and, calculated the decline correlativity according to pattern for every kind of test case.The ρ value that is produced changes in 0.05 to 0.98 scope.In addition, the phone of same model can be used for measuring the correlation between signals that receives by each antenna in typical indoor environment.In the zone that local PCS service provider covers, carry out test.
Especially, with reference to figure 7, will measure " pattern " correlation results based on the measured value in the test cabinet 20 and compare with the numerical value that from the primary field measured value, obtains.For example, view 700 comprises: corresponding to the transverse axis 702 of measured pattern ρ value and corresponding to the Z-axis 704 of field ρ value; Phone 706 has the single dipole antenna that is connected to separation vessel and measures down in non line of sight (" NLOS ") situation (indoor); Phone 708 has two pairs of dipole antennas measuring at the top under near sighting distance (" LOS ") situation, and described antenna has the interval of 0.05 λ; Phone 710 has two pairs of dipole antennas measuring under the NLOS situation, described antenna has the interval of 0.05 λ; Flip phone 712 has an exterior antenna and an inside antenna of measuring under the NLOS situation; Flip phone 714 has an exterior antenna and an inside antenna of measuring under the NLOS situation; Phone 716 has the exterior antenna of two tubbiness measuring under the NLOS situation; And phone 718, have exterior antenna and an inside antenna of a tubbiness of under the NLOS situation, measuring.Therefore, view 700 illustrates: for big ρ value scope, the ρ that calculates based on pattern and field data is nearly all above each other.
Because the correlativity between a measured pattern ρ and the ρ, these results have confirmed and can carry out lab investigation according to described embodiment, so that the diversity performance of the wireless device of dual-antenna diversity has been enabled in estimation, and need not be by means of a test on a large scale.
In addition, with reference to figure 8, form 800 comprises the measured radiation pattern of use from test telephone, the example of the ρ 802 that calculates for different channels model 804.In this case, channel model 804 comprises indoor environment, urban district Microcell, urban macro sub-district and the highway macrocell with external base station transceiver.In addition, each channel model 804 all comprises different variable set 806.In this case, for example, variable 806 comprises polarized wave m, angle spread σ and polarizability XPR.Should be understood that, the statistical value that is used for channel model comes from people such as Kalliola at " Angular Power Distribution and Mean Effective Gainof Mobile Antennas In Different Propagation Environments " (IEEETransactions on Vehicular Technology, Vol.51, No.5, in September, 2002) measurement of carrying out in merges its content at this by reference.Based on these result of calculation, described equipment and method provide a kind of robust fashion, and the decline correlativity between two antennas in its use complex radiation pattern estimation mobile environment is so that characterize the diversity performance of the wireless device of having enabled diversity.
