摘要

本文对一种新的代价函数作了研究，提出一种适用于多电平ＱＡＭ（ＭＱＡＭ）信号的自恢复均衡算法，克服了ＣＭＡ算法对相位不敏感的缺点；并在此基础上提出了两种改进的均衡算法：概率算法和混合算法．理论分析和计算机模拟表明这两种算法的收敛性能优越，而且误码性能与传统的ＬＭＳ均衡算法一致，是两种很实用的均衡算法．

Abstract

In this paper

a new cost funcion is investigated and a new self-recovery equalization algorithm based on this function is proposed for Multi-Lecel QAM modulation. Tthis equalization algorithms based on the new algorithm are proposed. Analysis and computer simulations show that the convergence performanve and symbol error performance of the blind equlation algorithm are better than those of CMA algorithm

and are the same as those of the convertional LMS equalization algorithm. So these new equalization algorithms are very useful for practive use.
