Abstract

Orthogonal frequency division multiplexing is an effective technique for high rate of data transmission but it is inherent with performance degradation for multipath fading channel. Antenna diversity is an effective and practical applied technique to provide good SNR in the effect of multipath fading. In recent next generation (4G) communications, the most promising technique to support high rate of data transmission can be the combination of “Space Time diversity” with “OFDM” systems. STBC-OFDM will provide a very reliable and robust transmission over scattering environment in particular coding over time, frequency and space domain. In this paper transmitter diversity has been applied through Alamouti matrix on binary phase shift keying (BPSK) modulated data and STBC-OFDM system is used for the BER performance evaluation. MATLAB simulation is performed for each system and the results are compared for the BER performance and finally the conclusion is drawn based on the simulated results.
