Performance Comparison of MIMO Systems over AWGN and Rician Channels with Zero Forcing Receivers

Multiple-Input Multiple-Output (MIMO) systems havebeen emerged as a technical breakthrough forhigh-data-rate wireless transmission. The performance of MIMO system can be improved by usingdifferent antenna selection so as to provide spatial diversity. In this paper, the performance of MIMOsystem over AWGN (Additive White Gaussian Noise) and Rician fading channels with ZF receiver isanalyzed using different antenna configurations. The bit error rate performance characteristics of Zero-Forcing (ZF) receiver is studied for M-PSK (M-ary Phase Shift Keying) modulation technique usingAWGN and Rician channels for the analysis purpose and their effect on BER (Bit Error Rate) have beenpresented.
