In this paper, the performance of two multi-user MC-CDMA wireless communication systems in frequency selective channel are analyzed and compared. The two MC-CDMA systems use two different space-time block codes with transition matrices of size 2×2 and 4×4. Both systems utilize two transmit antennas. Analytical and simulation symbol error rate results are obtained for the two systems for BPSK and QPSK modulations.
