Feedforward equalizer for DFE based detector

摘要

A system includes a first filter that receives an input signal and comprises N taps to filter postcursor inter-symbol interference (ISI) of the input signal. S taps of the N taps have a coefficient that is limited between −1 and 0. S and N are integer values greater than or equal to 1. N is greater than or equal to S. A decision feedback equalizer includes a decision circuit that communicates with the first filter. A second filter communicates with an input and an output of the decision circuit.
