Analysis on Blind Equalization Performance of CMA Algorithm
Cai Li-jin · Communications technology · 2011
ISI and ICI are inevitable in wireless channel due to the effect of multi-path transmission and limited bandwidth.Blind equalization,as a novel adaptive equalization technique without the aid of training sequence,could equalize the channel distortions.With the principle of Bussgang blind equalization,the Bussgang-like blind equalization algorithms based on CMA is discussed in this paper.Simulation on the algorithm with Simulink indicates the influence of step size on the convergence performance and accuracy,the smaller the step size,and the slower the convergence,and vice versa.
