Abstract
Recently a Maximum Entropy MaxEnt algorithm and its derivation called WNEW algorithm were presented by the same author It was shown that the MaxEnt and WNEW algorithm have improved equalization performance compared with Godard’s reduced constellation algorithm and the sign reduced constellation algorithm In this paper a new equalization method is proposed for the 16QAM and 64QAM input constellation based on the WNEW algorithm which is extended with some polynomials of the equalized output and optimized with the mean square error criteria According to simulation results the new equalization method leads to over 15 dB advantage in the residual Intersymbol Interference compared to the results presented by Godard 10 dB advantage compared with the WNEW algorithm and 5 dB advantage compared with the MaxEnt algorithm
