Performance Evaluation Of Mimo Systems With Varying Number Of Transmitting Antennas

Abstract: In this paper it evaluates the BER (bit error rate) performance of MIMO system. MIMO uses multiple transmitting antennas, multiple receiving antennas and the space time block codes to provide diversity. MIMO transmits signal encoded by space time block encoder through different transmitting antennas. These signals arrive at the receiver at slightly different times. Spatially separated multiple receiving antennas are used to provide diversity reception to combat the effect of fading in the channel. This paper presents a detailed study of diversity coding for MIMO systems. Finally, these STBC techniques are implemented in MATLAB and Simulation results displays the BER report of performance of MIMO system with varying number of transmitting antennas and MSE performance for two channels under Rayleigh fading environment.
