直扩系统折叠匹配滤波器设计

Design of folded-structure matched filter in DS system based on FPGA

在直扩系统中如何利用有限的硬件资源来实现高动态环境下的快速捕获是工程实现中的重点和难点。文中介绍折叠结构匹配滤波器在直扩接收机中的应用,并说明其基于FPGA的设计方法。

In this paper, a digital matched filter based on FPGA is proposed. This folded-structure matched filter provides a fast aequision in a high dynamic DS receiver.
