Simulation of MIMO Antenna Systems in Simulink

MIMO system is an emerging technology in wireless communication. MIMO uses multiple transmitting antennas, multiple receiving antennas and the space time block codes to provide diversity. This paper simulates the MIMO system with different modulation techniques. The Simulink model of MIMO system is designed to evaluate the performance in terms of error ratio and MSE performance for two channels under Rayleigh fading environment. The Simulink is highly configurable, easily extensible, and can generate exhaustive performance and complexity measurements. This paper presents a detailed study of diversity coding for MIMO systems. Simulation results are presented which indicate that the Error ratio of system using BPSK modulation technique is decreasing more rapidly as compared to the system using QPSK modulation technique.
