Abstract
A system and method is provided for using phase adjustment in non-causal channel equalization in a communications system. The method comprising: receiving a serial data stream input; comparing a bit value in the serial data stream determined at a first phase with respect to a clock, to a bit value determined at a second phase; determining the optimal phase for the determination of bit values; and, using the optimal phase to determine subsequently received bit values. Typically, the serial data stream is encoded with forward error correction (FEC). Then, the method further comprises: FEC decoding the bit values determined at a plurality of phases. Determining the optimal phase for the determination of bit values includes calculating an error rate associated with the phases and, defining the optimal phase as the phase associated with a low error rate.
