基于TH码的UWB信号的同步捕获方案

Timing Acquisition Scheme of UWB Based on TH Code

提出一种基于TH码匹配滤波器的UWB信号的同步捕获方案,采用适于密集多径信道的PLPD I算法。通过对TH码匹配滤波器输出进行PLPDI操作并进行门限比较,寻找多径分量所存在的区间,在建立的同步窗中对样点进行门限判决,在同步实现的同时获得多径分量所存在的区域及其幅度。该方案实现较为简单,仿真表明该方案的可行性。

A timing acquisition scheme of UWB based on TH cede matched filter is proposed, at the same time the algo- rithm named PLPDI is proposed too. The scheme aims to find the distribution time segment of UWB muhipath components and establish the sweep window , as the timing acquisition is achieved , the estimate of the delays and attenuations of muhipath compoment can be found by threshold decision. The scheme is simple in utilizilition, and the results of simulation shows the scheme effectness.
