Decision-feedback equalization for digital communication over dispersive channels.

Abstract : A decision-theory approach to the problem of digital communication over known dispersive channels is adopted to arrive at the structures of the optimal and two sub-optimal receivers: the 'conventional' and 'decision- feedback' equalizers, both employing matched and transversal filters. The conventional equalizer is similar to some equalization modems finding current application, while the new decision-feedback equalizer (as its name implies) utilizes its previous decisions in making a decision on the present baud.
