Abstract

The MIMO system has been used widely in the modern telecommunication, but there is serious Inter-symbol Interference (ISI) in the process of communication. Blind equitation algorithm has been utilized to eliminate the ISI. This paper researched MIMO system based on constant modulus algorithm (CMA) 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.
