Abstract

A novel nonlinear blind equalizer for linearly modulated digital communication is proposed. The equalizer employs a ring decision device that feeds back a weighted sum of past ring decisions to approximately cancel intersymbol interference (ISI) in the present signalling interval. Simple adaptive algorithms for blindly adapting the coefficients of the equalizer are presented
