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.

Code division multiple access (CDMA) communication is rapidly replacing time- and frequency-division methods as the cornerstone of wireless communication and mobile radio. Theory of Code Division Multiple Access Communication provides a lucid introduction and overview of CDMA concepts and methods for both the professional and the advanced student.

Emphasizing the role CDMA has played in the development of wireless communication and cellular mobile radio systems, the author leads you through the basic concepts of mobile radio systems and considers the different principles of multiple access–time division, frequency division, and code division. He then analyzes three major CDMA systems–direct sequence (DS) CDMA systems, frequency hopped (FH) CDMA systems, and pulse position hopped (PPH) CDMA systems. Other topics covered include:

• Spread spectrum (SS) technology
• Forward error control coding
• CDMA communication on fading channels
• Pseudorandom signals
• Information theory in relation to CDMA communication
• CDMA cellular networks

Complete with useful appendices providing analyses of the moments of CDMA system decision statistics, Theory of Code Division Multiple Access Communication is a ready reference for every engineer seeking an understanding of the history and concepts of this key communications technology.

This book is a collection of papers dealing with the theoretical aspects of optical communications. It is divided into four parts: Information and Communication Theory for Optical Communications; Coding Theory and Techniques; Characterizing, Measuring, and Calculating Performance in Optical Fiber Communication Systems; and Modulation Formats and Detection. Each paper is self-contained, and will give the reader a clear picture of the treated topic, an overview of the theoretical aspects, and an idea of the most recent advances.

"Excellent coverage: captures the gamut from propagation science to network planning." -- Nikil Jayant, John Pippin Chair in Wireless Systems, Georgia Tech

"For those already installing 3G systems, I recommend it be rushed into print." -- Reed Fisher, formerly of Bell Labs and father of the cell phone

"Engineers will find this is a much-needed integrated approach to understanding 3G technologies." -- Ken Smolik, Technology Specialist, Banner & Witcoff, Ltd.

This book gives network managers and 3G workers a select background in spread spectrum technology, empowering them to make real-world design, purchasing, and deployment decisions. Assuming only that W-CDMA is the preferred interface, the authors make a point of grounding 3G technologies in the fundamentals of propagation characteristics, physical layer functionalities, and spectrum requirements, so readers can confidently tackle soft handover, power control, sectorization, and message flows.

Written by authors with deep experience in data communications design and development, this jargon-free look at W-CDMA:
* Spells out what providers must know to enable wireless data speeds 40 times the current level
* Shows how to integrate U.S., European, and Pacific Rim flavors of 3G for worldwide roaming access
* Explains how spread spectrum functions best in data transmission
* Covers vital links between GSM and W-CDMA systems
* Reviews and unpacks IMT-2000 interface proposals
