摘要
本文研究第三代移动通信中的宽带码分多址(WCDMA)系统移动台(MT)接收的若干关键技术。包括数字匹配滤波器、RAKE接收机、同步电路设计和数字成型滤波器等。主要内容分为五个部分。第一部分介绍了第三代移动通信系统的发展、体系结构、基本特征和关键技术。第二部分在对匹配滤波器的工作原理及其在CDMA系统中的应用进行综述总结的基础上，根据WCDMA系统的信道设置，介绍了一种用于MT接收的时分数字匹配滤波器。第三部分研究了一种基于时分数字匹配滤波器的RAKE接收机。建立了RAKE接收机的系统模型，分析了其工作原理，给出了其实现方案，并在此基础上介绍了一种支持宏分集的RAKE接收机的实现原理，同时对工程实现过程中需要考虑的一些问题进行了探讨。第四部分研究WCDMA MT接收的同步电路设计。首先分析了相干和非相干延迟锁定环的性能，接着给出了一种DLL跟踪环路的实现方案和一种载波跟踪环路的设计方法。第五部分介绍了一种FIR成型滤波器的设计和实现方法。
The researches in this dissertation focus on several key technologies in MT receiving of wideband code division multiple access(WCDMA) system, including digital matched filter, RAKE receiver, design method of synchronization and digital shaping filter. The main contents consist of six parts. The first part focuses on the development, organization, features and the key technologies of the third generation mobile communication. In the second part, based on the comprehensive survey of the operational principle of matched filter and its application in CDMA system, we present a time division digital matched filter according to the channel setting for WCDMA system, which is used for mobile tenninal(MT) receiving. The third part deals with a RAKE receiver based on the time division digital matched filter. We set the system model of the RAKE receiver, analyze its principle and propose its implementation scheme. Furthermore, we study a RAKE receiver which supports macro diversity. Some problems which must be concerne
d in the system realization are also discussed in this part. In the forth part, we study the problems of synchronization in WCDM MT receiving. First, we analysize the performance of coherent and noncoherent DLLs, then we give an implementation scheme of DLL and a design method of carrier tracking loop.The design methods and a implemention scheme of a FIR shaping filter is proposed in the fifth part.
