This paper deals with BER analysis of MIMO Systems under different communication channels Additive White Gaussian Noise (AWGN) and Fading channel (Rayleigh and Rician). MIMO system uses Zero Forcing (ZF) decoder and Maximal Ratio Combining (MRC) at the receiver and encoded Alamouti STBC is used as transmit diversity. System performance in diverse modulation techniques such as BPSK, QAM and PAM is examined using MATLAB. Inorder to improve the bit error rate and symbol error rate , we also proposed LMS filtered based BPSK and LMS filter MRC. The simulated result shows that comparing the three different channel conditions, Rician fading channel has better performance. The Experiment results are obtained using Matlab software tool
