Abstract
A synchronization detector is disclosed wherein a portion of the received data stream is parallel loaded into a sequence generating means. The sequence generating means provides a local synchronization sequence that is compared to the transmitted synchronization signal, and an error count is tallied. If the number of errors occurring in a predetermined 'window' is below a predetermined threshold, a synchronization detect signal is asserted. However, if the errors in a predetermined window exceed the threshold, the sequence generating means is reloaded with another portion of the received data stream and the process is repeated until the synchronization detect signal is asserted.
