Novel Blind Channel Equalization Iterative Algorithm Based on Decorrelation Method
In digital wireless communications, Blind equalization without training sequence or any priori knowledge of the channel dynamics has become a topic problem, and one of its most important performance criterions is the convergence speed. Traditional constant modulus algorithm (CMA) with many advantages is a popular blind equalization approach, but its slower convergence rate is unsuitable for the compensation of the multipath fading wireless channels. In this paper, a novel blind channel equalization algorithm is presented by introducing a decorrelation factor into the equalization process. The improvement in convergence rate as well as residual MSE of the proposed algorithm is confirmed by computer simulation results.
