摘要 IR-UWB(Impulse Radio-Ultra Wide Bandwidth,冲激无线电-超宽带技术)是短距离无线通信中一个非常有前景的技术。该文介绍了几种有关IR-UWB信号的比较新型的调制技术,例如伪混沌编码跳时调制、脉冲位置幅度调制、自适应调制等,分析了其调制方法的基本原理,并给出了误码率分析。 UWB technology is an attractive technology for the short distance wireless communications. This paper introduces several new modulation schemes , such as pseudo-chaotic time hopping (PCTH) modulation, pulse position amplitude modulation (PPAM) and adaptive modulation. It also presents the principles of the modulation schemes, and the error probability is as well as presented.
