提出了一种新的非参量不相关检测器,这样不用估计干扰的方差就可以得到判决门限。对用了非参量检测器的DC/CDMA系统与用了传统检测器的DC/CDMA系统进行了对比。从仿真结果看,当干扰的方差不能精确估计时,非参量检测器的性能明显优于传统检测器的性能。
A new nonparametric irrelevant detector is proposed so that the decision threshold can be obtained without estimating the variance of interference. The DC / CDMA system with a non-parametric detector is compared with a DC / CDMA system with a conventional detector. From the simulation results, when the variance of the interference can not be estimated accurately, the performance of the non-parametric detector is obviously better than that of the traditional detector.
