Direct-Sequence Spread-Spectrum Multiple-Access Communication Mode Based on Residue Number System and Its Performance

本文建议并分析了一种基于剩余数系统的直接序列扩频多址通信方式；利用特征函数方法分析了在信道中存在加性高斯白噪声和多用户干扰情况下系统的差错特性，给出了平均差错概率的表达式；最后通过数值计算结果对建议的扩频通信方式和Ｍ进制正交码直接序列扩频通信方式在系统结构、差错特性、多址能力等方面进行了比较。

A direct-sequence spread-spectrum multiple-access communication mode based on residue number system is presented. The approximation for the multiuser probability of error are obtained by characteristic function method when the channel noise is a combination of additive white Gaussian noise (AWGN)and multiple-access interference.The numeric results show the comparisions of the performance of the proposed system in this paper and the system proposed by P.K.Enge.
