Abstract :
Space frequency block codes (SFBC) are very much efficient in overcoming the effect of frequency selective fading channel in a wireless communication system. In this paper, bit error rate performance analysis is carried out for a SFBC-OFDM system with MSK and GMSK modulation schemes. Results are evaluated numerically for SISO and MIMO communication links. It is shown that, for a fixed bit error rate the improvement in SNR for both SFBC coded MSK and GMSK modulation is noticeable. Also the receiver sensitivity is evaluated for system BER. It is shown that sensitivity improves for the change in code rate but remains nearly same for the same combination of transmit and receive antennas both for SFBC coded MSK and GMSK modulation scheme.
