Jianping Zhang, Xiaoling Zeng · 2018
This article propose and use the Modify Constant Modulus Algorithm (MCMA) and Decision-Directed Least Mean Square (DD-LMS) joint equalization Algorithm to balanceInter-Symbol-Interference (ISI) at the receiving end of 16-QAM.We analyzed 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.
