Claim One:
1. A far-end cross-talk canceller for a precoded multiple-input multiple-output communications system comprising a plurality of receivers, each receiver comprising: a first received signal that is filtered by a first feed-forward equalizer (FFE); a first decision device, comprising a first modulo device and a first slicer, to process the output of the first FFE to compute a first tentative decision by adding the output of the first FFE to a first error signal obtained by computing the difference between the input and output of the first slicer of the first decision device; a first far-end cross-talk (FEXT) canceller filter to filter a second tentative decision from an adjacent receiver; a first summer to subtract the first FEXT canceller filter output from a delayed version of the first FFE output to compute a first FEXT-free signal; and a second decision device, comprising a second modulo device and a second slicer, to process the first FEXT-free signal to compute a first output symbol.
