摘要

提出了一种用于处理多速率通用移动通信系统(UMTS)信号的传统去相关检测器的推广方法。首先，考虑到UMTS的两层传播码，对多址干扰进行了表征。为此，定义了初等相互关系。在此基础上，推导了描述UMTS信号匹配滤波器(MF)输出的方程，并解释了所提出的多速率去相关检测器策略。该检测器推广了标准的单速率去相关检测器，优于其他常用的接收器，如最小均方误差(MMSE)接收器和相关接收器。

Multirate decorrelating detector for UMTS

A generalization of the conventional decorrelating detector, designed to deal with the multirate Universal Mobile Telecommunications System (UMTS) signal, is presented. First, the multiple access interference (MAI) is characterized taking into account the two-layered UMTS spreading codes. To this end, the elementary cross-correlation is defined. On the basis of this elementary cross-correlation, the equations that describe the UMTS signal matched filter (MF) outputs are derived and the proposed multirate decorrelating detector strategy is explained. This detector, that generalizes the standard single-rate decorrelating detector, outperforms other commonly employed receivers like the minimum mean-square error (MMSE) receiver and the correlation receiver.
