说明：  一种新的基于数据可靠性判决引导的CMA盲均衡算法，该算法在计算量增加不多的前提下，能同时获得较快的收敛速度和较小的稳态误 差，特别适用于MQAM数字通信系统，且实现起来简单
(A new decision-directed based on the data reliability of the CMA blind equalization algorithm, which increased more than in the calculation of the premise, it could also get a faster convergence rate and smaller steady-state error, especially for MQAM digital communications system, and simple to implement)
