An Introduction to Ultra Wideband Communication Systems, by Jeffrey H. Reed

Introduction to Ultra Wide Band Communication Systems offers acomprehensive view of UWB system design, that spans propagation, antennas,receive and transmitter implementations, standards and regulations,interference issues, simulation techniques, modulation and multiple access,network issues, and applications. This book encompasses all areas of designand implementation of UWB systems crucial to their successful testing anddeployment.UWB offers unique capabilities, such as extremely high data rates, and buildingpartitions and ground penetrating transmission. The FCC acknowledged thebenefits of UWB when, in 2001, regulations were modified to allow thetransmission of UWB signals. The standardization effort has recently come tofruition with the creation of a new, regulated communication standard.However, a new standard brings along with it new regulations and equipment;and the design of UWB systems is very different than traditionalcommunication systems. The current general reference books for design ofcommunication systems are insufficient, and in some cases could be misleadingto a UWB designer. Furthermore, there is a tremendous need to unify thediverse concepts and fields of study embedded in the design of UWB systems.

From the Back Cover

The definitive, end-to-end guide to high-performance UWB system design

With the FCC's approval of new ultra wideband standards, UWB is poised to drive breakthroughs in both commercial and military communications. However, UWB system design is radically different from conventional communications system design, and traditional design guides are insufficient—or even misleading. Now, for the first time, there's an authoritative and comprehensive guide to the latest best practices in UWB system design.

Authored by leading-edge experts and researchers, Introduction to Ultra Wideband Communication Systems systematically addresses every major issue engineers will face in designing, implementing, testing, and deploying successful systems. The authors cover propagation, antennas, receiver and transmitter implementation, standards and regulations, interference, simulation, modulation and multiple access, networking, applications, and more.

Topics include

  • UWB fundamentals: technology, system components, standards/regulations, and the controversies surrounding UWB

  • Never-before-published techniques for addressing propagation, modeling, and channel simulation

  • UWB antenna design—including surprising differences between UWB and narrowband systems

  • Effective transmitter design reflecting UWB's modulation principles

  • Receiver design for impulse UWB systems—including key differences from conventional carrier-based systems

  • In-depth coverage of interference, focusing on "peaceful coexistence" between UWB and narrowband radio systems

  • Practical simulation techniques that avoid unacceptably long simulation times

  • How UWB's physical layer capabilities impact the performance and design of upper layers

  • Real-world UWB applications and case studies of existing systems

This book is the definitive resource for every professional involved with UWB: RF engineers concerned with UWB's impact on radio design; experienced computer and DSP engineers moving into radio communications; systems engineers who must master UWB radio link design; and technical managers who must clearly understand the challenges they'll face in delivering successful systems.

PrefacePreface

To a great extent, this book was inspired by the Defense Advanced Research Project Agency project called NETEX. The program manager, Stephen Griggs, recognized that far too little information about Ultra Wideband (UWB), particularly pulse-based UWB systems, appeared in the literature. Moreover, he believed that the UWB information available in the public domain is sometimes incorrect and misleading, particularly regarding interference issues with UWB. Thus, the program participants were encouraged to widely disseminate the results of the NETEX program to help clarify many of these outstanding issues. Much of the information presented in this book is a direct result of this program and other UWB research programs from Virginia Tech and the Army Research Lab.

UWB activity has picked up immensely since the Federal Communication Commission's 2002 decision to allow for the transmission of UWB and the subsequent standardization efforts with the Institute of Electrical and Electronics Engineers, Inc. Some see UWB as an enabling technology for new wireless applications that span from high-data-rate transmission of raw multimedia video to new location-aware, low-data-rate, and low-power communication of sensor data. Non-communication applications, such as through-the-wall imaging and ground-penetrating radar, also capture the imagination of researchers and entrepreneurs.

The controversy surrounding the standardization efforts illustrates the many debatable issues of UWB. From an academic perspective, many fundamental research issues remain unresolved, including the best modulation types for particular applications, efficient broadband antennas with a desirable form factor, propagation characteristics of UWB in various environments, the impact of UWB physical layer attributes on the networking layers, and the list continues. UWB will certainly be the subject of many theses and dissertations to come.

This book provides a broad technical view of UWB. Chapters 2 and 3 deal with simulation of propagation issues, modeling, and channel simulation, and much of this information is presented in the public domain for the first time. Chapter 4 focuses on antennas and outlines some surprising differences in antenna performance with respect to narrowband systems. Chapter 5 examines transmitter design issues and covers some of the basic modulation principles of UWB. Chapter 6 presents an overview of receiver design issues and explains how impulse UWB systems are particularly different from conventional carrier-based systems. Chapter 7 addresses the controversial interference issues of UWB; unlike traditional communications, UWB may intentionally transmit co-channel with other communication signals. Chapter 8 examines how to simulate UWB systems; such simulation requires more finesse because broadband signals encounter excessive simulation time if structured incorrectly. Chapter 9 describes how the physical layer capabilities of UWB impact the performance and design of upper layers. Finally, applications and case studies of existing UWB systems are addressed in Chapter 10.

We hope readers will find this book of interest and will check the web site (www.mprg.org/publications/Reed/UWBbook.shtml) for additional information about UWB and this book.

Acknowledgments

When writing a book, the authors usually have three groups of people upon whom they rely: those who support them financially, those who offer their advice, and those who contribute their skill.

We would like to acknowledge the Bradley Foundation for its financial support, through the Bradley Fellowship program, of Chris Anderson and Nathaniel August. We also offer our thanks to the National Science Foundation for its financial support, through an Integrative Graduate Education and Research Training grant (award DGE 9987586), for Michelle Gong and James Neel. Many of the authors also received funding via the Industrial Affiliates program of the Mobile and Portable Radio Research Group (MPRG) and through Virginia Tech VLSI for Telecommunications (VTVT).

We would especially like to thank our reviewers, whose comments and perspectives enriched this book: Robert Ulman of Army Research Labs, Krishna Balachandran of Lucent, Andy Molisch of Mitsubishi Electric Research Laboratories, Jiann-An Tsai of Samsung, Dennis Akos of Stanford University, and Laurence Milstein and Claudio da Silva of the University of California, San Diego. In addition, we offer our most sincere gratitude to the following

reviewers, who graciously gave of their time to review multiple chapters (some the entire book): Jonathan Cheah of femto Devices, Bruce Fette and John Polson of General Dynamics, Robert Aiello and Jason Ellis of Staccato Communications, Steven Sarraf of the U.S.~Army, and Mauro Biagi of the University of Roma ��La Sapienza.''

Our appreciation is extended to the students in the Spring 2003 advanced simulation course at Virginia Tech, who developed a simulation of a UWB communications system as a class project. The students involved in this effort were Ihsan Akbar, Ramesh Chembil, Jina Kim, Hyung-Jin Lee, Maruf Mohammad, James Neel, Muhammad Nizamuddin, and Sujay Sachindar. The results of their class project formed the first draft of the simulation chapter of this book. We also acknowledge students who helped with other research that led to the writing of this book: Ahmet Bayram, Vivek Bharadwaj, Brian Donlan, Jihad Ibrahim, Gaurav Joshi, Dave McKinstry, Ali H. Muqaibel, Joseph Noronha, Swaroop Venkatesh, and Liu Yang. We offer our thanks to Chris Sadler for helping with Matlab code used in some of the examples in the interference chapter.

Finally, special thanks goes Cyndy Graham of Virginia Tech's MPRG, who worked tirelessly to form something cohesive out of submissions from numerous authors (all with different working and writing styles), and to Lori Hughes, a freelance production assistant (lori@lorihughes.com), who deftly guided us through the production process. We also offer our utmost appreciation to Bernard Goodwin, Acquisitions Editor at Prentice Hall PTR, for his patience and his guidance.
