In MMSE equalization of Multiple-Input Multiple-Output(MIMO) system,imprecision due to finite sample size in the estimation of the sensor covariance matrix and the channel matrix has a negative impact on the detection of the transmitted data symbols.Independent Component Analysis(ICA) is proposed to refine the conventional equalizer with optimal delay calculation method.The simulation results indicate that this algorithm possesses better robustness,less calculation complexity and more outstanding equalization.
