BER Analysis of MIMO-OFDM System using BPSK Modulation under Different Channel with STBC, MMSE and MRC

Abstract: A hypothesis is characterize in this paper with reference to Alamouti-STBC and MMSE (mean square error equalizer) for the advancement the BER (bit error rate) in the MIMO-OFDM system. So as achieve the desired outcomes. The different fading channel Rayleigh and AWGN have been used to calculate BER analysis of MIMO system. The prospective system is simulated in matlab and consider in terms bit error rate with signal to noise ratio (SNR). Finally this Alamouti-STBC technique evaluates for performance according to their BER using BPSK modulation schemes.
