摘要超宽带 (UWB)技术是无线通信中的一个非常有发展前途的技术。介绍了 UWB的概念和工作原理、UWB信号的时域特征和频域特征 ,分析了 UWB常用的两种调制技术 :脉冲幅度调制 (PAM)和脉冲位置调制(PPM)的详细过程。 Ultra WideBand(UWB)is the technology that has developing fore grand in wireless communication.This paper presents the concept and the basic principles of UWB,including UWB signal features both in time and frequency domains,then analyzes general two approaches of modulation--pulse position modulation(PPM)and pulse amplitude modulation (PAM).And finally discusses main features of UWB communication in detail.
