摘　　要：超宽带(Ultra Wideband,UWB)通信系统的脉冲宽度很窄(纳秒量级),单个脉冲能量非常小,若单纯在接收端做同步,则很难实现。因此收发两端联合设计,通过数据帧前置导频同步码是比较理想的选择,一方面能辅助系统快速捕获实现同步,另一方面为后续均衡提供训练序列。插入导频序列后会带来一定的功率和效率损失,但从全局来看,是值得的。The pulse width is very narrow and the monopulse energy is very low for ultra wideband（UWB） communication system, so it is difficult to realize synchronization in receiver terminal. An ideal selection is to insert guide code before data frame through codesiguing receiver and transmitter. It can help system to realize synchronization quickly, on the other hand it also provides train sequence for subsequent balance. The guide sequence inserting may bring some loss in power and efficiency, but it is worthy for the full system.
