In this paper, we present a multi-carrier CDMA system using differential QPSK modulation in urban mobile environment. From the analysis and simulation results, we find that the performance of the multi-carrier CDMA system is improved with the aid of guard interval, especially in the case of existing strong interference from other users. Compared with the traditional DQPSK-DS-CDMA system, the advantage of multi-carrier CDMA is also evident.
