摘要
描述了UWB通信系统的信号和信道模型,重点讨论了传统非传输参考(TR)和传输参考体制下的超宽带通信系统的同步捕获问题,总结比较了这两种体制的主要同步方法,最后阐明了超宽带同步研究中的主要问题及其研究方向,从而为超宽带同步捕获的研究提供一定的参考。
In this paper, the models for the propagation channel and the acquisition signal for Ultra Wideband (UWB) communication systems are described firstly. Then,the acquisition issues of VWB communication system are discussed, which under nontransmitted reference and transmitted reference scheme respectively. The main synchronization of these two system are also compared. At last, the main problems and potential research direction in UWB acquisition are pointed out, and thus make sense to the research on acquisition problems of UWB communication system.
