In this paper, the authors present a study for the error rate performance of Multi Carrier Direct Sequence Code Division Multiple Access (MC DS-CDMA) system in conjunction with Maximum Ratio Combining (MRC) over Nakagami-m multipath fading channel. Multiple transmit and receive antenna structures are employed at both the transmitter and the receiver sides to provide spatial diversity The multipath fading is considered to be correlated among different elements at the receive antenna array. In the proposed receiver, two types of diversities are considered; the path, and spatial diversities. A closed form one-fold integration, which could be solved numerically without the need for simulations, is derived for the BER performance of the system.
