UWB: Theory and Applications

UWB: Theory and Applications
Ian Oppermann (Editor), Matti Hämäläinen (Editor), Jari Iinatti (Editor)
ISBN: 0470869178
October 2004

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.

Fundamentals of Global Positioning System Receivers: A Software Approach

Fundamentals of Global Positioning System Receivers: A Software Approach
James Bao-Yen Tsui
ISBN: 0471706477
December 2004

The Second Edition of this acclaimed publication enables readers to understand and apply the complex operation principles of global positioning system (GPS) receivers. Although GPS receivers are widely used in everyday life to aid in positioning and navigation, this is the only text that is devoted to complete coverage of their operation principles.

The author, one of the foremost authorities in the GPS field, presents the material from a software receiver viewpoint, an approach that helps readers better understand operation and that reflects the forecasted integration of GPS receivers into such everyday devices as cellular telephones. Concentrating on civilian C/A code, the book provides the tools and information needed to understand and exploit all aspects of receiver technology as well as relevant navigation schemes:
* Overview of GPS basics and the constellation of satellites that comprise the GPS system
* Detailed examination of GPS signal structure, acquisition, and tracking
* Step-by-step presentation of the mathematical formulas for calculating a user’s position
* Demonstration of the use of computer programs to run key equations
* Instructions for developing hardware to collect digitized data for a software GPS receiver
* Complete chapter demonstrating a GPS receiver following a signal flow to determine a user’s position

The Second Edition of this highly acclaimed text has been greatly expanded, including three new chapters:
* Acquisition of weak signals
* Tracking of weak signals
* GPS receiver related subjects

Following the author’s expert guidance and easy-to-follow style, engineers and scientists learn all that is needed to understand, build, and operate GPS receivers. The book’s logical flow from basic concepts to applications makes it an excellent textbook for upper-level undergraduate and graduate students in electrical engineering, wireless communications, and computer science.

UMTS Security

UMTS Security
Valtteri Niemi, Kaisa Nyberg
ISBN: 0470847948
December 2003

The Universal Mobile Telecommunication System (UMTS) offers a consistent set of services to mobile computer and phone users and numerous different radio access technologies will co-exist within the UMTS system’s core network – security is, therefore, of the utmost importance.

The book focuses on the standardized security features of UMTS and brings together material previously only available in specifications, design documents and presentations in one concise form. In addition, this unique volume also covers non-standard implementation specific features that allow differentiation between operators and manufacturers.

  • Describes the security solutions specified for UMTS
  • Provides a comprehensive presentation of the UMTS security specifications and explains the role of the security functionality in the UMTS system
  • Presents the UMTS security system in its totality from the theoretical background through to the design process
  • Discusses the new security features included in Release 4 and 5

By providing a unified treatment of the security services provided by the UMTS system, this volume will provide invaluable information and have instant appeal to planners, constructers and implementers of UMTS networks, and developers and analysts of application oriented security services that make use of UMTS communication networks. It will also be of considerable interest to postgraduates and researchers of modern communication security technology.

Queueing Theory with Applications to Packet Telecommunication

Queueing Theory with Applications to Packet Telecommunication
Daigle, John N.
ISBN: 0387228578
July 2005

This book is an efficient introduction to fundamental concepts and principles underlying the behavior of queueing systems and its application to the design of packet-oriented electrical communication systems. In addition to techniques and approaches found in earlier works, the author presents a thoroughly modern computational approach based on Schur decomposition. This approach facilitates solution of broad classes of problems wherein a number of practical modeling issues may be explored.

Key features of communication systems, such as correlation in packet arrival processes at IP switches and variability in service rates due to fading wireless links are introduced. Numerous exercises embedded within the text and problems at the end of certain chapters that integrate lessons learned across multiple sections are also included. In all cases, including systems having priority, developments lead to procedures or formulae that yield numerical results from which sensitivity of queueing behavior to parameter variation can be explored. In several cases multiple approaches to computing distributions are presented.

is intended both for self study and for use as a primary text in graduate courses in queueing theory in electrical engineering, computer science, operations research, and mathematics. Professionals will also find this work invaluable because the author discusses applications such as statistical multiplexing, IP switch design, and wireless communication systems. In addition, numerous modeling issues, such as the suitability of Erlang-k and Pade approximations are addressed.
