Abstract
A system and method for decision feedback equalizer (DFE) tap adaptation. An input signal is received at a DFE of a receiver, wherein the input signal comprises a serial bit stream of encoded symbols. Data samples and error samples are taken from the input signal and the data samples and the error samples are aligned establish a plurality of pairs of data samples and error samples, wherein the data sample and error sample of each of the plurality of pairs of data samples and error samples are from locations in the serial bit stream of encoded symbols that are known to be uncorrelated with each other. The DFE tap weights are then adjusted based upon the plurality of pairs of data samples and error samples.
