| 摘 要： | 本文对一种新的代价函数作了研究，提出一种适用于ＭＱＡＭ调制信号的变步长的判决引导的盲均衡算法。理论分析和计算机模拟表明变步长判决引导的盲均衡算法的收敛性能及误码性能均优于ＣＭＡ算法，并与传统的ＬＭＳ均衡算法的性能一致，是一种很实用的均衡算法。

| Abstract: | In this paper, a new cost function is investigated and a variable step size Decision Directed equalization algorithm based on this function is proposed for MQAM modulation. Analysis and computer simulations show that the convergence performance and symbol error performance of the blind equalization algorithm are better than those of CMA algorithm, and are the same as those of the conventional LMS equalization algorithm. So the variable step size Decision Directed equalization algorithm is very useful for practice use. |
