ABSTRACT:
In order to provide a simple and reliable means of frame synchronization in a serial data communication system, which avoids the problem of ‘bit-stuffing’ in known HDLC systems, the data communication system comprises a transmitter arranged to transmit data as a sequence of frames, each frame comprising a synchronization section and a payload section of data, and the transmitter including in the synchronization section of each frame a count value of a sequence of count values (a part of a predetermined code sequence), wherein successive frames contain successive count values (other parts of the predetermined code sequence) The receiver includes a FIFO buffer for storing three successively received frames, and a processor for assessing the stored data within the frames in order to locate and recognize the count values, whereby to synchronize to the received frames.
