摘　　要：提出了一种针对短波QAM信号,采用基于信噪比切换的改进CMA-DDLMS盲均衡算法,对该算法进行了具体介绍,该算法具有残余误差小、收敛速度快的特点,并对该算法进行了仿真验证。A modified CMA-DDLMS blind equalization algorithm based on the automatic switch according to the SNR for QAM signals in short wave is discussed. The algorithm has small residual error and fast convergence performance. Its good performance is confirmed by simulation and comparison.
