IETF次数相同时，采用选择性映射和部分传输序列方法降低MC-CDMA信号峰均值比的性能对比。-IETF number is the same, selective mapping and some ways to reduce transmission sequence MC-CDMA signal peak performance than the mean contrast.

communication system is expected to increase the service, the quality improvement and also the capacity, using spread spectrum communication system is one of the method to fulfill that demand. This quality and capacity factor will depend on the numb

This paper studied the carrier-frequency offset effect on the performance of asynchronous multicarrier direct-sequence code-division multiple-access (MC-DS-CDMA) systems with aperiodic random spreading and correlated Rayleigh fading. This paper also
