摘要
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.
