Abstract
A receiver includes a matched filter, and an M of N detector is coupled to the matched filter for determining potential synch pulses occurring M of N times. A cluster detector is coupled to the M of N detector for determining a plurality of synch pulse clusters based upon the potential synch pulses. A peak detector is coupled to the cluster detector for determining respective synch pulses based upon the synch pulse clusters. Each synch pulse cluster has a cluster width associated therewith, and the peak detector removes synch pulse clusters exceeding a cluster width threshold.
