This resource gives professionals a comprehensive understanding of the simulation and evaluation methods used in the design and development of today's mobile communication systems. Professionals get in-depth discussions on digital modulation techniques, transmission schemes, discusses multiple access protocols, cellular telecommunication systems, and cutting-edge software radio communication systems.

This practical resource gives professionals the information needed to analyze and evaluate the performance of satellite links and networks, and to understand the issues and limitations of IP/ATM over SATCOM technology, used for the transmission of multimedia information services. The book examines current and future land mobile satellite (LMS) communication systems, and the techniques necessary to support reliable and efficient communication.

Since 1998 enormous progress has been made in the development of third generation mobile phone networks. This study provides a comprehensive introduction to wideband code division multiple access theory, systems and applications.

The fast-growing demand for advanced high-speed, multimedia wireless services accessible to anyone, anywhere, requires the building of new "third generation" mobile communications systems. Critical to the development of these systems is the establishment of standards that will allow personalized, user-friendly wireless access to a widely varied telecommunications infrastructure. This volume details the technology underlying these standards and provides an in-depth description of all the elements required to create third generation systems and networks.

A study of OFDM, including a comparison with other forms of single carrier modulation methods. It provides the design guidelines needed to maximise benefits from this technology. There is practical advice on how to plan, design and use OFDM to make wireless multimedia communications happen. It offers a solid base for assessing the performance of wireless OFDM systems; explains how OFDM signals are formed using the Inverse Fast Fourier Transform, how the cyclic extension mitigates the effects of modulation, and how windowing can limit out-of-band radiation; discusses the sensitivity of OFDM to synchronization errors; examines the basics of direct sequence and frequency hopping CMDA, helpful in understanding combinations of OFDM and CDMA; explains Multicarrier CDMA, various transmitter architectures, and the pros and cons compared to other CDMA techniques; and includes a discussion of the combination of OFDM and frequency hopping CDMA to get a multiple access system with similar advantages to direct sequence CDMA.

Written by a leading authority in the communications industry, this single-source reference provides in-depth understanding of the fundamental and advanced principles behind the development of a global personal communication system capable of providing convenient multimedia communications to individuals in every corner of the world. The book explores the behaviour of macro-, pico-satellite- and overlay-cellular systems and gives the reader the knowledge needed sucessfully to address related transmission system issues and problems. Introductory chapters review statistical radio channel modes, present mathematical and analytical models for evaluating co-channel interference probability, discuss multiple and random access protocols, identify and describe a wide range of CDMA systems, and much more. More advanced, solution-oriented sections cover OFDM system applications, analyze MC-CDMA in a wireless environment, outline basic antenna system and diversity schemes, and present an analytical model used to evaluate bit-error probability. The reader also gains a solid understanding of the theory and applications associated with wireless broadband multimedia communications (WBMC) and satellite communications (SATCOM).

This is the first comprehensive analysis of the practical applications of Code Division Multiple Access to today's and tomorrow's wireless communications systems. Presenting CDMA as a multiple access protocol for wireless indoor, outdoor, and land-mobile satellite communication systems, it provides engineers, researchers and students with a complete overview including a comparison of wired and wireless network systems, details of hybrid CDMA, and techniques to enhance the performance of CDMA-based systems. Complete with 180 illustrations, 400 equations, practical examples, and appendices.
