ABSTRACT:
A technique for determining an arbitrary delay in a source code word propagated over a channel that introduces the arbitrary delay in the source code word to produce a received code word. The technique is based upon a multiple-shift algorithm to determine the delay by a coarse synchronization process to locate synchronization as contained within a composite code pattern, and a fine synchronization process to pinpoint the delay by examining shifts in the source code word used to form the composite code pattern.
