提出并采用修正恒模算法（ MCMA）和判决引导的最小均方算法（ DD－LMS）联合均衡算法，对16－QAM系统接收端的码间干扰进行均衡。分析了联合均衡的技术的实现方式和切换门限，对四种不同的均衡算法进行了仿真实验。仿真结果表明，MCMA与DD－LMS联合均衡算法较之其它三种均衡算法，能够将剩余误差迭代得更小，而且可以有效地修复传输过程中产生的相位偏移。

This article proposed the Modify Constant Modulus Algorithm ( MCMA) and Decision-Directed Least Mean Square ( DD-LMS) joint equalization Algorithm to balance Inter-Symbol-Interference ( ISI) at the receiving end of 16-QAM.We an-alyzed the joint equalization technology implementation and switching threshold.Also we had carried on simulation experiments of four different equalization algorithms .The simulation results show that MCMA and DD-LMS joint equalization algorithm can get smaller residual error iteration, also can effectively repair the transmission process of phase shift.
