摘要

提出了一种用于移动终端WCDMA FDD下行接收的新型RAKE接收机结构。与传统的RAKE手指方法相比，FlexRake架构使用单个相关器引擎和存储基带I/Q采样的整个延迟扩展的缓冲区来执行信号接收。这允许每个跟踪的多路径按顺序散布完全处于同一阶段的代码。所提出的接收器架构的主要优点是灵活的多路径分配、符号同步操作和简单的接收器控制。

A flexible RAKE receiver architecture for WCDMA mobile terminals

This paper presents a novel RAKE receiver architecture for WCDMA FDD downlink reception in mobile terminals. In contrast to the conventional RAKE finger approach, the proposed FlexRake architecture performs signal reception with a single correlator engine and a buffer which stores the entire delay spread of the baseband I/Q samples. This allows each of the tracked multipaths to be despread sequentially with codes that are exactly in the same phase. The main benefits of the proposed receiver architecture are flexible multipath allocation, symbol-synchronous operation, and straightforward receiver control.
