摘      要:A faster, more robust framing detector for the multiplexing format of 2.048 Mb/s PCM systems is proposed. Existing framing detectors look for a seven bit syncword. By simply storing 512 bits and searching for the combination of two seven bit syncwords, the search time is improved by a factor of four and operation is permissible with a greatly increased channel error rate.
