摘要
本文主要研究了存在多径衰减时ＣＤＭＡ的检测问题。首先，提出了一种新的检测方法———多检测器部分相关检测。其次，对其进行了性能分析。最后在数值计算中与文献［１］的方法进行了比较，说明本文提出的检测方法在系统的复杂性和性能方面较文献［１］优越。
In this paper,we discuss detection problem of CDMA in multipath fading.First,a new method of detection——multi-sensor partially coherent detection is presented.Secondly, the performance of the system is analyzed using this method.Finally,the result is compared with that of literaturethrough computer simulation.It is shown that the multi-sensor partially coherent detection is better than the method of the literaturein terms of the complexity and system performance.
