研究了一种用于W-CDMA系统干扰抑制的统计处理方法。干扰的主要一阶统计量，即pdf函数是通过使用接收样本的高阶统计量（HOS）来估计的。该估计又导致导出样本的最佳非线性处理器，以增强期望用户的检测性能。的数学模型的过程中，提出和相对于传统的线性检测器的检测器的相对渐近效率计算。还提供了一些数值结果，以显示所提出的非线性处理，适用于基于UMTS的接收机可实现的增强。
A statistical processing method is considered for interference suppression in W-CDMA systems. The major first-order statistic of interference, namely, the pdf function is estimated by use of higher-order statistics (HOS) of the received samples. This estimate, in turn, leads to deriving the best non-linear processor of the samples for enhanced detection performance of the desired user. A mathematical model for the process is presented and the relative asymptotic efficiency of the detector with respect to the conventional linear detector is computed. Some numerical results are also provided to show the achievable enhancement by the proposed nonlinear processing as applied to UMTS-based receivers.
