一种适用于TH-PPM UWB快速捕获方案

A Scheme of Rapid Timing Acquisition for TH-PPM UWB Signal

同步是超宽带通信系统的关键技术之一。针对高速TH-PPM超宽带通信系统,利用TS-TDT算法捕获速度快、比特翻转法同步精度高的特点,给出了融合两种算法优势的同步捕获方案。仿真分析结果说明该方案能有效降低捕获时间,提高同步精度。

Timing acquisition is one of the key technologies in Ultra wide-band communication system. This paper proposed a scheme which integrated two algorithms. The scheme used the rapid acquisition advantage of TS-TDT （time-shift-TDT） algorithm and high precision of bit reversal algorithm to realize timing acquisition according to the system of high speed of TH-PPM UWB communication system. The simulation and analysis results show the scheme efficiently reduces the acquisition time and enhances the performance of timing acquisition
