Improved algorithm for blind channel equalization
Panshi Tang, Jianping Li, Fan Yang · 2013
This paper describes the blind channel equalization for constant modulus algorithm mathematical model and principle. Focusing on the CMA blind equalization slow convergence and convergence error, the paper analyzes and simulates recent years' constant modulus algorithm and improved algorithm based on residual error and leak CMA nonlinear transformation algorithm. The results show that, compared with the constant modulus algorithm improved algorithm can improve the convergence speed.
