摘要：Multiple-antenna systems are currently enjoying increasing popularity and widespread applications in which, it can improve the capacity and reliability of wireless receiver section. MIMO systems utilize multiple antennas to increase the diversity gain of wireless communication systems. Space Time Block Coding (STBC) is a MIMO-based algorithm, which efficiently exploits spatial and temporal diversity. In this paper , the analytical results for the bit error rate (BER) of M-ary Phase Shift Keying(MPSK) in a slow ,flat Rayleigh fading channel for a multiple-input multiple-output (MIMO) system using an Alamouti transmission scheme and Maximal Ratio Combining scheme is studied and simulated using matlab tool box.This paper analyses the performance of Generalized Space-time sum of squares (GSTSoS) receiver section scheme. The simulation results show that as the number of receivers is increased the Bit Error Rate(BER) of the system is decreased.
