【摘要或目录】：The application of ultra-wideband (UWB) technology to low-cost short-range communications presents unique challenges to the communications engineer. The impact of the US FCC’s regulations and the characteristics of the low-power UWB propagation channels are explored, and their effects on UWB hardware design are illustrated. This tutorial introduction includes references to more detailed explorations of the subject.
TH－PPM UWB就是源于Robert A. Scholtz的研究工作，对UWB稍有了解的人都应该清楚。文章的内容远不止摘要所介绍的。文中介绍了UWB的发展和特点，澄清了一些概念，涉及的内容涵盖天线设计、链路预算分析（比较详细）、脉冲的生成、传播环境、数字接收机，并且对UWB面临的挑战也作了详细的分析。文章着重从电路实现的角度来探讨UWB中的问题；对于初入门的人来说是很好的综述，对于熟悉的人来讲也定会有所收获。至少本人有“相见恨晚”的感觉。共53篇参考文献

【摘要或目录】：Ultra-wideband (UWB) radio is a fast emerging technology with uniquely attractive features inviting major advances in wireless communications, networking, radar, imaging, and positioning systems. By its rulemaking proposal in 2002, the Federal Communications Commission (FCC) in the United States essentially unleashed huge “new bandwidth’’ (3.6–10.1 GHz) at the noise floor, where UWB radios overlaying coexistent RF systems can operate using low-power ultra-short information bearing pulses. With similar
regulatory processes currently under way in many countries worldwide, industry, government agencies, and academic institutions responded to this FCC ruling with rapidly growing research efforts targeting a host of exciting UWB applications: short-range very high-speed broadband access to the Internet, covert communication links, localization at centimeter-level accuracy, high-resolution ground-penetrating radar, through-wall imaging, precision navigation and asset tracking, just to name a few. This tutorial focuses on UWB wireless communications at the physical layer. It overviews the state-of-the-art in channel modeling, transmitters, and receivers of UWB radios, and outlines research directions and challenges to be overcome. As signal processing expertise is expected to have major impact in research and development of UWB systems, emphasis is placed on DSP aspects.
PWAM的作者L.Q Yang. 此文早于上面一篇文章，风格也完全不同。文章详细而又全面地给出了一个典型UWB系统的解决方案：调制方式、信道模型、脉冲成型、定时、同步、信道估计、Rake接收、PWAM、非相干接收机、多天线、多址接入、容量分析、组网、实现等。根据文中的方法完全可以搭建一个完整的UWB平台。总共84篇参考文献，你认为怎样呢？读完这些参考文献，你也成UWB专家了
值不值自己看吧。 |
