Abstract :
In this paper we use the same analytical method to study a generic STBC-CDMA system. A comprehensive analysis has been carried out to derive the bit error rate performance expression of such a system under MAI and flat fading considering maximal ratio combining scheme at the receiving side and examined the performance of the system with the correlation values for different code (OC code, m-sequence, gold code) and variable user. The channel dependent interference value is also considered with ABBA, Extended Alamouti code (EAC) and other possible combination of STBC code and compare the BER performance.
