基于MIMO系统恒模盲均衡算法的研究及改进

he MIMO system has been used widely in the modern telecommunication, but there exsits serious Inter-symbol Interference (ISI) in the process of communication. In order to eliminate the ISI, blind equitation algorithm has been used widely. This paper researched MIMO system based on constant modulus algorithm and introduced variable step-size theories by analyzing the defects of the blind equitation algorithm. This paper has proposed two improved algorithms and verified the ability of convergence through computer simulation .
