Abstract
A system and a method are provided for non-causal channel equalization using error statistics. The method comprises: receiving a non-return to zero (NRZ) data stream input encoded with forward error correction (FEC); establishing a plurality of thresholds to generate a first bit estimate; comparing the first bit estimate in the data stream to a second bit value received prior to the first bit; comparing the first bit estimate to a third bit value received subsequent to the first bit; in response to the comparisons, determining the value of the first bit; FEC decoding the determined first bit value; and, using FEC error statistics to adjust the thresholds by evaluating the number of errors associated with a plurality of three-bit sequence combinations.
