Abstract
A system and method for processing wideband data within digital FM transceiver. A digital FM demodulator within the transceiver produces a demodulated information signal in response to the FM signal. The digital FM receiver also includes a wideband message processing section for recovering message information from the demodulated information signal. A word register circuit within the wideband message processing section stores one or more repetitions of a message word recovered from the demodulated information signal. During operation of the FM receiver in a control channel mode, a dotting detector within the wideband processing section is used for detecting a first dotting sequence within the demodulated information signal. Similarly, the dotting detector serves to detect a second dotting sequence within the demodulated information signal during operation in a voice channel mode. A word sync sequence is also identified within the demodulated information signal prior to storage of the one or more repetitions of the received message word within the word register circuit. A reconstructed message word is then generated by comparing corresponding bits within the one or more repetitions …
