Abstract
A signal synchronization system is disclosed which samples an incoming stream containing binary information at a sampling rate which is an integral multiple of the bit information rate. This system correlates the sequences of the sampled bit pattern with a predetermined sequence to produce a measure of the dissimilarity between the sampled and the predetermined sequences. Synchronization of a local sampling clock with the incoming binary information is achieved by making phase adjustments to the local sampling clock which are functions of both the magnitude of dissimilarity and the time of measurement.
