The purpose of this book is to acquaint the student to wireless personal communications, one of the fastest growing fields in the engineering world. Technical concepts, which are at the core of design, implementation, research and inventing wireless communications systems are presented.
From the Back Cover
As cellular telephones become commonplace business tools, interest in wireless technology is booming. This book responds to that demand with a comprehensive survey of the field, suitable for educational or technical use. Materials are drawn from academic and business sources, numerous journals, and an IEEE professional reader. Extensively illustrated, Wireless Communications is filled with examples and problems, solved step by stepand clearly explained.
Wireless Communications covers the design fundamentals of cellular systems, including issues of frequency reuse, channel assignments, radio propagation, and both analog and digital modulation techniques. Speech coding, channel coding, diversity, spread spectrum, and multiple access are also discussed. A separate chapter is devoted to wireless networking, including SS7 and ISDN.
Beyond theory,Wireless Communications offers practical reference sections, including:
* Complete technical standards for cellular, cordless telephone, and personal communications systems
* International standards for Europe, the Americas, and the Asia-Pacific region
* Noise figure calculations and Gaussian approximations of spread spectrum CDMA interference
* Mathematical tables, identities, and the Q, erf, and erf functions
* Glossary of abbreviations and acronyms
* Full list of references
This book is designed for use in graduate and undergraduate classrooms, but is also suitable for use by professional engineers and technicians. It can be used for both teaching and reference, and is also appropriate for the interested cellular phone consumer who wants to understand the technology.

Typically, there are over twenty radio systems on board the average commercial jet aircraft dealing with communication, navigation and surveillance functions. Very high frequency (VHF) air-to-ground communication is usually the main method of information and control exchange between pilot and air traffic control. Satellite and high frequency radio links are used to complement this system for long range or oceanic information exchanges. Other communications systems are required between the airline operation centre and the pilot and sometimes between the passengers and the ground. A comprehensive guide to current systems, networks and topologies, this book covers application requirements for communication and related radio-navigation and surveillance functions in aeronautical systems. There is also an insight into future possibilities as technologies progress and airspace operation and control scenarios change. Ideal for civil aviation authorities, airspace management providers and regulatory organizations, Aeronautical Radio Communication Systems and Networks will also appeal to aircraft and radio equipment manufacturers and university students studying aeronautical or electronic engineering.
Key features:
- Provides a broad and concise look at the various communications systems on board a typical aircraft from a theoretical, system level and practical standpoint with worked examples and case studies throughout.
- Considers all types of aircraft from light aircraft to large commercial jets and specialised supersonic aircraft.
- Looks at existing airport radio communication infrastructure and proposals for new very high bandwidth radio applications within the airport environment.
- Provides a complete list of formulae for engineering design analysis and quick checks on system performance

Book Description
The Optical Society of America (OSA) and SPIE The International Society for Optical Engineering have awarded Govind Agrawal with an honorable mention for the Joseph W. Goodman Book Writing Award for his work on Nonlinear Fiber Optics3rd edition.
Nonlinear Fiber Optics, 3rd Edition, provides a comprehensive and up-to-date account of the nonlinear phenomena occurring inside optical fibers. It retains most of the material that appeared in the first edition, with the exception of Chapter 6, which is now devoted to the polarization effects relevant for light propagation in optical fibers. The contents include such important topics as self- and cross-phase modulation, stimulated Raman and Brillouin scattering, four-wave mixing, modulation instability, and optical solutons. A proper understanding of these topics is essential for scientists and engineers interested in various aspects of lightwave technology.
Such an ambitious objective increased the size of the book to the extent that it was necessary to create a separate but complimentary book, Applications of Nonlinear Fiber Optics, which is devoted to applications in the domain of lightwave technology.
This revised edition of Nonlinear Fiber Optics should serve well the needs of the scientific community including graduate students in Optics, Physics, andElectrical Engineering, engineers in the optical communication industry, and scientists working in fiber optics and nonlinear optics.
* Only book dealing with Nonlinear Fiber Optics
* Comprehensive up-to-date coverage of the entire field
* Problems at the end of each chapter suitable for a course
* Focus on fundamental aspects
* Can be used by graduate students doing research in or taking courses in nonlinear optics and optical communications
