Performance comparison of space-time coded MC-CDMA systems

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/spl times/2 and 4/spl times/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.
