摘　　要：研究了剩余数系统扩频多址系统在多径Ｒａｙｌｅｉｇｈ慢衰落信道中采用最大比组合分集接收方式时，系统的差错性能。并且同Ｍ进制正交码扩频通信系统的差错性能进行了比较。Concerned in this paper is a direct sequence spread spectrum multiple access communication system based on residue number system. The system activates in a multipath fading channel, and a RAKE receiver structure with maximum ratio combination is used for demodulation. Approximation to the error probability is given and compared that of the direct sequence spread spectrum communication system with the M array orthogonal modulation scheme.
