定时同步是UWB通信系统中至关重要的问题，定时偏差和抖动将严重影响接收机性能。一般定时同步分为捕获和跟踪两个阶段。在捕获阶段，要求接收机快速搜索信号到达时间，并根据搜索结果调整接收机定时.-Timing Synchronization UWB communication systems is of vital importance to the issue, timing error and jitter will seriously affect the receiver performance. Timing Synchronization generally divided into two stages to capture and track. In the capture stage, the request receiver Quick Search signal arrival time, and adjust search results according to the receiver from time to time.
