摘要
超宽带系统使用纳秒级的短脉传输数据,能够克服短距离通信中的多径影响,特别适合短距离高速数据通信。针对超宽带系统的快速低复杂度同步问题,基于非相干脉冲超宽带系统,结合相干超宽带系统中的一些快速捕获算法,提出一种新的快速同步方法。在子积分窗口部分重叠时,该同步方法能够比文献[1]中的方法更快速达到同步。经仿真验证,本方法在同步性能上均优于现有方法。
The Ultra-Wide Band (UWB) system carrying data by nanosecond short pulse, could overcome multi-path effect, which is a promising candidate for short-range high rate data communication. A novel rapid synchronization method was proposed, aiming at solving the low complexity synchronization issue. The proposed method based on non-coherent UWB system, takes' account of several fast capture methods in coherent UWB system. When the sub integrate window overlaps partly, this proposed method could achieve synchronization more rapidly than Reference [1] 's. By simulation, the proposed method has outperformed the current one[1].
