Constant Modulus Algorithm; Decision Directed LMS; Slowly Time-Varying Channel.


In this paper, a semi-blind channel equalization method is proposed to overcome the local minima problem of Con stant Modulus Algorithm(CMA). Simulation results show that: this novel semi-blind equalizer achieves better perfor mance compared with general CMA and Decision-Directed Least Mean Square algorithm(DD-LMS) in terms of Inter symbol Interference (ISI) and Bit Error Rate(BER).
