Abstract

In this paper, a novel segment processing matched filter algorithm is proposed by optimizing the differential digital matched filter (DDMF) structure. According to the new architecture, the computation complexity of DMF can be reduced to approximately 30% of that of the DDMF for fixed coefficient PN sequence. To further reduce the area and power consumption, several strategies have been employed. This design was successfully tested as a component for an acquisition circuit to be used in Global Positioning System (GPS) receiver (Braasch and van Dierendonck, 1999), and was able to operate at up to 100MHz

基于分段处理的数字匹配滤波新算法

本文通过对差分数字匹配滤波器(DDMF)结构的优化，提出了一种新的分段处理匹配滤波器算法。根据新结构，对于固定系数PN序列，DMF的计算复杂度可以降低到DDMF的30%左右。为了进一步减少面积和功耗，采用了几种策略。该设计已成功测试为用于全球定位系统(GPS)接收器的采集电路的组件(Braasch和van Dierendonck, 1999)，并且能够在高达100MHz的频率下工作
