摘要
重点介绍了数字差动匹配滤波器 (DDMF)的结构和原理 ,提出了一种采用 DDMF进行 PN捕获的方案。研究结果表明 :此方案能实现快速捕获 ,与传统的数字匹配滤波器 (CDMF)相比能节约硬件资源。
The architecture and theory of digital differential matched filter (DDMF)are introduced, a scheme of PN code acquisition by using DDMF is proposed.Research results shows that this new scheme can not only make acquisition rapid,but also save the hardware resource in comparison with the conventional digital matched filer.
