1. A method comprising performing by circuitry for use in a receiver, said circuitry comprising a decision feedback equalizer (DFE) and a feed forward equalizer: determining values of tap coefficients used by the DFE based on: an error signal that is based on an output of the feed forward equalizer and an estimated inter-symbol-correlated (ISC) signal; and a set of error vector(s), where each error vector in the set of error vector(s) represents a difference between estimated symbols generated in the receiver and expected symbols; determining a frequency of occurrence of each of a plurality of error vectors in the receiver; and selecting a most-frequently occurring subset of the plurality of error vectors as the set of error vector(s).
