| 摘 要： | 针对正交小波变换分数间隔盲均衡算法(FSE-WT-CMA)收敛速度慢且存在局部收敛问题,提出了一种引入支持向量机的正交小波分数间隔盲均衡算法(SVM-FSE-WT-CMA).该算法通过对分数间隔盲均衡器的输入信号进行正交小波变换,以降低信号的自相关性,并且利用支持向量机将盲均衡问题转化为全局最优的支持向量回归问题,采用...

| Abstract: | Due to the disadvantages in low convergence rate and local minima being found in the blind equalization algorithm based on fractionally spaced orthogonal wavelet transform and constant modulus algorithm(FSE-WT-CMA),a blind equalization algorithm based on fractionally spaced orthogonal wavelet transform with support vector machine(SVM-FSE-WT-CMA) is proposed.This algorithm can reduce the signal autocorrelation by the orthogonal wavelet transform to the input signal of fractionally spaced blind equalizer,util... |
