基于正交小波变换的分数间隔盲均衡算法
Blind Fractionally Spaced Equalization Algorithm Based on Orthogonal Wavelet Transform
摘要
Abstract
In order to overcome the slow convergence speed and larger mean square error (MSE),a fractionally spaced constant modulus blind equalization algorithm is proposed based on orthogonal wavelet transform, with analyzing the features of wavelet transform and fractionally spaced equalizer based on constant modulus algorithm (FSE-CMA). The proposed algorithm integrates orthogonal wavelet transform with T/2-FSE-CMA. The convergence rate of the proposed algorithm can be improved via fully using the de-correlation ability of wavelet transform and the bigger sampling rate of received signals of fractionally spaced equalizer. The proposed algorithm has faster convergence and smaller mean square error than baud spaced equalizer based on CMA(BSE-CMA) and T/2-FSE-CMA. The efficiency of the proposed algorithm is proved by computer simulation in underwater acoustic channels.关键词
