In this paper we introduce a new nonlinear adaptive equalizer which uses for input signal and impulse response of forward and feedback filter a Delta Modulation (DM) and Delta Sigma Modulation (DSM) incremental encoding with binary (+1,-1) or ternary (+1,0,-1)representation,respectively.DM-based approach appears to be promising for implementation simplicity,as no multiplications or multi-bit additions are required neither for filtering nor for adaptation.In addition,a simple coding allows to remove the equalizer feedback section.The system performance is comparable with that of the corresponding non-incremental equalizer.
