Definitions
- a method that facilitates feedback loop cancelation in a repeater environment comprises: receiving repeater transmitter leakage signal and receive signal at M number of receivers; storing the received signals as Ns number of time samples; appending the Ns time samples with zero valued samples to for a size NFFT array; performing a fast Fourier transform (FFT) on the received zero appended blocks to generate FFT bins; applying M number of complex spatial receive weights on the M number of receivers to generate weighted receiver signals on a bin by bin basis for the FFT bins; combining the weighted receiver signals to generate a composite weighted signal; producing a post-cancellation receive frequency bin for use in generating automatic gain control (AGC) output frequency bins; applying spatial weighting to the AGC output frequency bins to produce weighted transmit frequency bin arrays; performing an inverse FFT on the transmit frequency bins to produce time domain series that are transmitted to M receivers and summed at the M receivers for cancellation.
- FFT fast Fourier transform
- one or more components may be combined into a single component providing aggregate functionality or divided into several separate sub-components, and any one or more middle layers, such as a management layer, may be provided to communicatively couple to such sub-components in order to provide integrated functionality.
- Any components described herein may also interact with one or more other components not specifically described herein but generally known by those of skill in the art.
