BOOK EXCERPT:
Over the past 20 years UWB has been used for radar, sensing, military communications and niche applications. However, since the FCC ruling in 2002, which allowed the commercial operation of UWB for data communications, UWB has changed dramatically. Implementation oriented, this volume explores the fundamentals of UWB technology with particular emphasis on impulse radio (IR) techniques. It explains the key physical layer aspects of UWB technology, especially in communications and in control applications, and examines the multiple access (MAC) issues which are emerging as a hot area for practical UWB systems. Offers practical information about implementation Addresses issues of modulation possibilities, appropriate circuits for UWB, an example circuit design, MAC protocol issues and use of UWB for positioning applications Includes a literature survey examining books, articles and conference papers presenting the basic features of UWB technology and current systems Features a patent database search providing a historical perspective to the state-of-the-art technology UWB Theory and Applications will be indispensable to researchers interested in the practical issues of UWB technology and realistic assumptions of UWB, as well as engineers interested in implementing UWB devices.

BOOK EXCERPT:
Ultrawideband (UWB) communication systems offer an unprecedented opportunityto impact the future communication world. The enormous available bandwidth, the wide scope of the data rate / rangetrade-off, as well as the potential for very low-cost operation leading topervasive usage, all present a unique opportunity for UWB systems to impactthe way people and intelligent machines communicate and interact with theirenvironment. The aim of this book is to provide an overview of the state of the art of UWBsystems from theory to applications. Due to the rapid progress of multidisciplinary UWB research, such an overviewcan only be achieved by combining the areas of expertise of severalscientists in the field. More than 30 leading UWB researchers and practitioners have contributed tothis book covering the major topics relevant to UWB. These topics includeUWB signal processing, UWB channel measurement and modeling, higher-layerprotocol issues, spatial aspects of UWB signaling, UWB regulation andstandardization, implementation issues, and UWB applications as well aspositioning. The book is targeted at advanced academic researchers, wireless designers, and graduate students wishing to greatly enhance their knowledge of allaspects of UWB systems

BOOK EXCERPT:
Low Power UWB CMOS Radar Sensors deals with the problem of designing low cost CMOS radar sensors. The radar sensor uses UWB signals in order to obtain a reasonable target separation capability, while maintaining a maximum signal frequency below 2 GHz. This maximum frequency value is well within the reach of current CMOS technologies. The use of UWB signals means that most of the methodologies used in the design of circuits and systems that process narrow band signals, can no longer be applied. Low Power UWB CMOS Radar Sensors provides an analysis between the interaction of UWB signals, the antennas and the processing circuits. This analysis leads to some interesting conclusions on the types of antennas and types of circuits that should be used. A methodology to compare the noise performance of UWB processing circuits is also derived. This methodology is used to analyze and design the constituting circuits of the radar transceiver. In order to validate the design methodology a CMOS prototype is designed and experimentally evaluated.

BOOK EXCERPT:
UWB (ultra-wideband) has been investigated for many decades but only recently has it become commercially viable. With the advent of WiMedia UWB technology and its associated standard specifications, the stage is set for the next generation of WPAN applications to take root. WiMedia UWB focuses on the ECMA-368 standard. Both PHY layer and MAC sublayers specified in this standard are explained in great detail. The book offers not only the facts about the requirements of the standard, but also the motivation and logic behind them. To give a comprehensive perspective of the UWB technology to the reader, other interrelated topics are also examined in this book. These include the history of UWB and its recent standardization attempts; UWB applications and advantages; UWB spectrum allocation and regulations around the world; UWB platform clients: Certified Wireless USB (CW-USB), Bluetooth, and WLP (WiMedia Link layer Protocol, which enables Internet Protocol over UWB); as well as some important implementation issues and considerations. As the first application of WiMedia UWB, CW-USB is given a special and more comprehensive treatment. This book is ideal for any engineer or engineering managers who are expecting to either develop a solution based on UWB or to integrate it with other devices. It will also be of interest to researchers who require an overview or an interpretation of the technology. One of the first books to describe the WiMedia standards (PHY and MAC) in detail A comprehensive approach to de-obfuscating the entire WiMedia UWB technology, from the PHY through the MAC, the MAC clients, the applications, and the regulations Includes a description of the CW-USB standard and its relation to WiMedia MAC Provides an up-to-date view of the UWB spectrum allocations and associated regulations around the world Derived from hands-on experiences in WiMedia UWB standards and system development efforts.

BOOK EXCERPT:
In this work new methods and criteria for the analysis of Ultra Wideband (UWB) components and systems are introduced. This permit to have a deeper insight into the component characteristics like signal distortion, ringing and dispersion, introduced by the non-ideal behavior of the UWB components over the wide frequency band. The developed analyses are the basis for correction and optimization strategies for the features of the UWB components and systems, compensating for their non-idealities.

BOOK EXCERPT:
Ultra Wide Band (UWB) technology has attracted increasing interest and there is a growing demand for UWB for several applications and scenarios. The unlicensed use of the UWB spectrum has been regulated by the Federal Communications Commission (FCC) since the early 2000s. The main concern in designing UWB circuits is to consider the assigned bandwidth and the low power permitted for transmission. This makes UWB circuit design a challenging mission in today's community. Various circuit designs and system implementations are published in this book to give the reader a glimpse of the state-of-the-art examples in this field. The book starts at the circuit level design of major UWB elements such as filters, antennas, and amplifiers; and ends with the complete system implementation using such modules.

BOOK EXCERPT:
Ultra wideband (UWB) communication systems are characterized by high data rates, low cost, multipath immunity, and low power transmission. In 2002, the Federal Communication Commission (FCC) legalized low power UWB emission between 3.1 GHz and 10.6 GHz for indoor communication devices stimulating rapid development of UWB technologies and applications. The proposed book Novel Applications of the UWB Technologies consists of 5 parts and 20 chapters concerning the general problems of UWB communication systems, and novel UWB applications in personal area networks (PANs), medicine, radars and localization systems. The book will be interesting for engineers and researchers occupied in the field of UWB technology.

BOOK EXCERPT:
Ultra-wideband (UWB) technology is a radio technology that uses electromagnetic waves with a very low power spectral density occupying a bandwidth of more than 25% of a centre frequency, or more than 0.5GHz, for short-range remote sensing, high-bandwidth communications or object positioning. The detailed analyses of state-of-the-art UWB technology has shown that this technology is very interesting and promising with a great application potential. Following these facts, our book attempts to present current and emerging trends in research and development of UWB systems. The book is focused on basic components of UWB systems such as antennas, filters, photonic approach for signal processing methods, as well as on some applications of UWB systems (human target analysis, cancer detection).
