N2 - OFDM-CDMA, the Orthogonal Frequency Division Multiplexing-Code Division Multiple Access, is a promising technology in mobile communication because of its abilities to combat the multi-path fading and narrowband interference. It has been proposed to use in many future communication systems. However, the high ratio of the peak power to the average power (PAPR) of the OFDM-CDMA signal, a special drawback of multi-carrier transmission, has prohibited its wider application. In this paper we focused on a new OFDM-CDMA system structure, which combines the Time Spreading Structure and Frequency Spreading Structure, called time-frequency spreading OFDM-CDMA. This system can achieve a much lower BER and PAPR compared to frequency spreading OFDM-CDMA. In this paper we give the simulation results of the new system, and show the performance improvement.
