| 摘 要： | 本文在ＣＭＡ算法代价函数的基础上，提出了一种适合于多电平正交幅度调制（ＭＱＡＭ）数字通信系统的递归步长多模盲均衡算法。研究表明，该算法在计算量增加不大的前提下，能同时获得较小的误码率和较小的稳态误差，而其收敛速度也比ＣＭＡ算法有较大的改善。

| Abstract: | In this paper,a recursive step multi-module blind equalization algorithm for MQAM digital communication system based on the cost function of CMA is proposed.Analysis and computer simulations show that the new algorithm can reduce the error rate and stationary error with only slightly increased calculation.And the convergence preformance is much better than that of CMA. |
