Demultiplex receiver apparatus

摘要

Accurate recovery of constituent data streams from a multiplexed serial data stream in which each symbol includes a nonintegral number of frames is accomplished by combining a coherently detected timing signal, which is a component of the received serial data stream, together with a bit clock signal and a symbol clock signal to locate a predetermined bit position within each frame. When the location of the predetermined bit position is determined, frame synchronization is complete and the constituent data streams are correctly demultiplexed from the multiplexed serial data stream. The timing signal has a pulse rate equal to the greatest common divisor of the frame and symbol rates.
