ABSTRACT Multiple antennas at both the transmitter and receiver are used in Multiple-Input and Multiple-Output MIMO system to improve the efficiency of wireless communication. MIMO technology has fascinated attention because it can significantly improves data throughput and wireless link coverage without additional transmit power or channel bandwidth constraint. In this research paper the performance of Rayleigh fading channel in 3x3 MIMO systems with channel capacity and probability error is studied and investigated. Space-Time Block Code STBC an effective and efficient transmit diversity scheme is implemented in MIMO systems to investigate and analyze the performance of fading channel. Simulation model is implemented and experiments are performed using MATLAB simulation software by varying the Signal to Noise Ratio SNR. Simulation result shows that the Rayleigh fading channel provides significantly higher channel capacity and lower probability error with a very little fluctuation with increasing SNR. The simulation result also clarify that 3x 3 MIMO systems outer perform with respect to channel capacity and probability error than 2X2 MIMO system which will be very helpful for high speed wireless communication system.
