摘要
A synchronization system within a dual antenna receiver employs two timing recovery loops each coupled to a different antenna input. Segment sync lock (detection of a segment sync in the data stream) by one timing recovery loop prompts selection of the timing error from the corresponding timing recovery loop for timing recovery within both loops. Both timing recovery loops are then synchronized utilizing the selected timing error. If sync lock for the selected loop is lost, the other loop is selected to provide timing error to both loops.
