The Correction Leakage CMA Blind Equalization by Average Instantaneous Error
Ying Xiao, Dong Yu-hua · 2010
CMA is a robust blind equalization algorithm in the communication system, but slow convergence rate and big steady-state residual error is the drawbacks of CMA. in this paper, a correction leakage CMA by average instantaneous error was proposed, The introduction of leakage factor in order to overcome the spread of errors generated in the weight update processing, at the same time, leakage CMA correct by average instantaneous error can further improve the performance of equalization. Computer simulation shows the effectiveness of the algorithm.
