摘　　要：基于Suehiro提出的一种多相正交序列构造方法,提出一种可转换为用于实际系统的多相扩频信号,给出了一种采用该扩频信号的多载波直接序列码分多址系统,分析了在瑞利衰落信道中的系统误比特性能,并对系统进行了仿真。Based on a new construction of multiphase orthogonal sequences proposed by Suehiro, a model of communication system is given in which the multiphase orthogonal sequences are converted into a multiphase Spread spectrum signal that can be used in communication system directly. The performance of multicarrier DS-CDMA in Rayleigh Fading Channel with polyphase orthogal spreading sequences is evaluated. And the simulation of the system is oerformed.
