Description

ABSTRACT:
A method of synchronizing digital data which includes periodic synchronization sequences. The first step in the method comprises determining the number of bit errors in relation to an ideal bit sequence in the synchronization sequence. A next step comprises using twice the chronological filtration from the resulting bit-error values to determine the timing of a synchronization sequence recognized in the digital data, allowing the data to be assembled block by block.
