恒模算法CMA的改进和比较

MA is one of the most commonly used Bussgang blind equalization algorithm,with low computational complexity, ease to accomplish in real-time and good performance in convergence.This paper started with channel distortion and inter-symbol interference channel,introduced the inadequacies of traditional blind channel equalization.Then introduces the basic principles of constant modulus algorithm (CMA) for blind channel equalization, including the analysis of the performance of CMA in MATLAB simulation. And it also Introduced several improvements CMA algorithm: Sign_CMA, MCMA, dual-mode MCMA respectively, and the performance compared with the CMA in MATLAB simulation.
