摘要 为了提高超宽带信号同步捕获的速度同时又能降低复杂度,提出一种新的超宽带"能量检测+搜索"两步同步捕获方法,分析了同步捕获过程,并对捕获时间进行了推导。通过仿真,表明新方法的平均捕获时间优于已有的算法。 To improve the acquisition speed and reduce the complexity for synchronization acquisition in Ultra-Wide Band （UWB） system, a novel two-step ＂Energy Detection ＋ Search＂ rapid acquisition method was proposed. The acquisition process was analyzed and the capture time was derived. The simulation results show that the average acquisition time of the new method is less than the existing algorithms.
