摘　　要：针对基于MBOK-TH-UWB实验通信系统介绍了一种实用的、新颖的多路并行同步捕获方案,分析了其电路的实现与性能,并给出部分仿真结果。与其他方法相比,该方法把同步捕获放在数字基带部分进行处理,降低了射频接收电路的设计难度,并具有良好的同步捕获性能。This paper introduced an effective and novel method of multiple-path synchronization acquisition in MBOK （ M-ary bi-orthogonal keying ）TH-UWB communication system, and analyzed the realization and performance of the circuit concretely. Meanwhile it also presented some partial simulation results. Compared with other methods, it processed the synchronization function with baseband circuit in FPGA. Which decreased the complexity of RF circuit design and enhanced performance of synchronization acquisition.
