Abstract :
In this paper, closed-form expressions of bit error rate (BER) performance of space-frequency block coded OFDM (SFBC-OFDM) systems are derived and evaluated over frequency selective fading channels. In the performance evaluation both M-ary phase shift keying (MPSK) and M-ary quadrature amplitude modulation (MQAM) are considered. Numerical results are provided for analysis and simulations. In addition performance of several forms of SFBC-OFDM system are also evaluated and compared.
