A MC-CDMA system can be configuration play important role in performance improvement in transmitter and receiver. One configuration is Transmit/Receive Diversity (TRD) which has been widely used due to its simplicity and good performance in huge load traffic. The performance of MC-CDMA systems with optimal TRD depends on their operational environments. By providing the receiver with multiple copies of the transmitted signal in space, MC-CDMA systems achieve spatial diversity and effectively mitigate multipath fading, thereby improves the quality and performance of the receiver. The desired spatial diversity order depends on the channel diversity, specially, the channel interference.
