摘　　要：针对高速TH-PPM的超宽带通信系统,提出了一种新颖的、可实现的多路并行同步捕获方案,分析了电路的实现与性能,给出了仿真结果。与其他捕获方案相比,该方案实现了射频电路与基带电路的完美结合,并把同步部分放到了基带部分进行处理,大大降低了接收射频电路处理的难度,并具有良好的捕获性能。The paper gave a novel and realizable scheme of multiple-path parallel synchronization and acquisition according to the system of high-speed TH-PPM UWB and analyzed the realization and performance of the circuit, meanwhile, provided emulational results. Compared with other schemes, this scheme realized the ideal-combination of baseband circuit and RF（radio frequency） circuit, which disposed the synchronization cell in baseband circuit and descreased the difficulty of RF disposal and had benign performance of synchronization and acquisition.
