Abstract

The digital word synchronization technique has a synchronization lock line (0,0..0) frame to lock to bits of information (B1 to B62). The lock line frame is sent as a sub channel at a low rate from a transmitter, and the receiver processes the full rate information and low rate synchronization lock line to produce a unique synchronized symbol for the end of the synchronized frame.
