Abstract :
In this paper, the performance of a space time coded multi-user MC-CDMA wireless communication system in frequency selective fading channels is analyzed. The space time code is a block code with a 4times4 transition matrix. Analytical and simulation symbol error rate results are obtained for the system with two transmit antennas. The analysis also shows that a more relaxed set of orthogonality conditions is sufficient for the spreading sequences
