Abstract
In order to overcome the slow convergence rate and large steady state error of present blind equalization
a new Blind Equalization Algorithm Based on Niched Genetic Algorithm and Wavelet Transform (NGAWT-CMA) was proposed.The proposed algorithm utilizes NGA to globally search and uses wavelet transform to improve convergence rate.The results of computer simulation proved the validity of the algorithm.
