ABSTRACT:
Synchronization can be acquired between a transmitting node and a receiving node on a time division multiple access communication link without the necessity for additional data bits in the data stream, by correlating the number of errors detected in any interval as revealed by the forward error correction field. Both synchronization bits and stuffing bits can be located without using any external frame timing information. Substantial bandwidth savings is achieved by the technique, which can be applied for arbitrary combinations of the number of input ports, the number of data bits per group, and the number of parity bits generated per group.
