For greatly overcoming the slow convergent rate and higher Mean Square Error(MSE) of Constant Modulus Algorithm(CMA), a Super-Exponential Iterative blind equalizer Based on Orthogonal Wavelet Transform(WT-SEI) was proposed on the basis of analyzing the futures of orthogonal wavelet transform and Super-Exponential Iterative(SEI) algorithm.The convergent rate of the proposed algorithm could be improved and its MSE could be reduced using the de-correlation ability of orthogonal wavelet transform and the whiten ability of SEI algorithm.The efficiency of the proposed algorithm is proved by computer simulation with time-varying channels.
