CDMA系统性能的精确分析

A Precise Analysis of Performances of Receivers in CDMA Systems

针对高斯假设的方法对多用户系统进行分析具有一定的局限性,对CDMA系统相关接收的性能进行精确分析,得到系统的误码率曲线。实际仿真结果表明,该分析方法比基于高斯假设的分析更精确。

Considering the limitation of the method based on Gaussian approximation for analysis of multiuser systems, a precise analysis is made of the performances of the receivers in CDMA systems, and the curves of bit error rate (BER) are obtained for the systems. A numerical simulation shows that the precise analysis method proposed in this paper is more accurate than the method that is based on Gaussian approximation.
