Now-a-days a speedy and more reliable communication links along with Multiple-input-multiple-output (MIMO) systems has become a prime concern in the field of Communication systems. As MIMO systems utilizes multiple number of antennas both at the transmitter and receiver, the necessary requirement to reduce the fading resulting from signal fluctuations in the channel is Diversity. In this paper the analysis of MIMO systems using STBC codes and OSTBC codes and measured the BER vs. Eb/N0 values have been carried out. The performance analysis of space–time block-coded multiple-input–multiple-output (STBC-MIMO) systems in different fading channels such as Rayleigh channel and Additive White Gaussian Channel (AWGN) channel is presented in this paper. Comparative analysis of average bit error rate (BER) of STBC-MIMO for binary phase-shift keying (BPSK), quadrature phase shift keying (QPSK) and Quadrature amplitude modulation (QAM) – both 8-QAM and 16-QAM are derived. Based on asymptotic analysis for both these fading channels, closed-form expressions of approximate average BER is obtained for different Eb/N0.
