摘要

本文研究了传统的匹配滤波器结构。提供了一种基于全球定位系统(GPS)接收机中多相形式匹配滤波器的采集电路。以较少的硬件资源为代价，提供了显著的同步速度优势。对于32×128多相形式匹配滤波器，关键路径延迟大约减少1/2，采样频率将增加一倍。

An acquisition circuit in Global Positioning System receivers

The conventional matched filter structures are investigated in this paper. An acquisition circuit based on the polyphase form matched filter in Global Positioning System (GPS) receiver is provided. At the cost of less hardware resource, the significant advantage in the speed of synchronization is offered. For 32×128 polyphase form matched filter, the critical path delay approximately reduces 1/2, the sample frequency would be double.
