BER Performance Analysis of Pre-MMSE Equalizer for MIMO System
Abstract: This paper investigates the performance analysis of linear ZF/MMSE and pre-minimum mean square error (MMSE) applied to wireless multi-input multi-output (MIMO) system. Here the numbers of transmitters are equal to receivers . Fading and interference effects can be combated with equalizers. The bit error rate characteristics for different MIMO matrices are simulated. Channel state information for the spatial-multiplexing system is used. Paper is focused on linear pre-equalization method. It demonstrates that pre-MMSE equalizer improves the BER performances.
