%X This paper analyzes the performance of average symbol error ratio (SER)of optimum combining for spatial diversity of OFDM system,modulated by M-QAM in flat Rayleigh multipath fading environment.This space diversity scheme which combines the received signals before discrete Fourier transformation greatly reduces the computation cost with small performance degradation.The received signals are weighted and combined to maximize the output signal-to- interference ratio with the number of interferences more than the number of antenna elements.Monte Carlo simulations represent the performance of average SER superior to maximum ratio combining.
