Abstract
The process of the present invention first synchronizes to incoming messages from the base station. The first data word is received and stored in the radiotelephone. The error code in the data word is next checked to determine if errors ex-ist in the word. If there are errors, the word is corrected.
This process is repeated on another data word and the second received word is compared with the first. If the words are not equal, the receiver remains on until at least two words are equal or the entire length of the message is received. If the words are equal, the word is processed by the radiotelephone and the receiver is turned off for the remaining portion of the message until the next synchronization word is to be received.
This process is repeated on another data word and the second received word is compared with the first. If the words are not equal, the receiver remains on until at least two words are equal or the entire length of the message is received. If the words are equal, the word is processed by the radiotelephone and the receiver is turned off for the remaining portion of the message until the next synchronization word is to be received.
