| 摘 要： | 捕获算法设计是超宽带通信系统同步的关键技术。在密集多径环境中,接收机捕获多径中任意一径,即可认为捕获成功。基于这一原理,设计了一种改进的捕获算法,利用形式更为简单模板信号,尽可能快速地搜索到多径中的任意一径,以达到较大程度地降低系统复杂度和减小平均捕获时间的目的。

| Abstract: | The design of acquisition algorithm is the key technology of UWB communication systems. In the dense multipath environments, it’s regarded as a successful acquisition that the receiver acquires any path in multipath. Based on this principle, this paper proposes an improved acquisition algorithm, which could find any path in the multipath as fast as possible by using simple template signals, thus achieving the reduction of system complexity and mean acquisition time. |
