Examining both the theoretical and practical side of CDMA engineering, this guide is designed for practicing RF and system engineers who should find the modular-oriented chapters on spread-spectrum multiple access technique, design and performance engineering, CDMA traffic engineering, and regulatory implications especially useful.

This guide to the theory and practice of RF power amplifier (PA) design for modern communications systems aims to help readers tackle PA design with confidence and save time in determining the cause of malfunctioning hardware. The book explores a unified approach to the classification of higher amplifier modes based on overdrive considerations. The text contains a complete survey of RF PA efficiency enhancement and linearization techniques and aims to help the reader design suitable matching networks which provide correct fundamental harmonic terminations for conventional high efficiency PA modes. It also provides an understanding of the class D, E and F modes and their feasibility at microwave frequencies and uses envelope simulation techniques to analyze the effects of distortion in overdriven PAS. Finally, the text discusses the maintenance of high efficiency operation at low points in an amplitude modulated signal envelope including detailed coverage of the Doherty, Chireix and Kahn techniques, it explores the possibilities and limitations of linearization methods and analyzes PA stability and oscillation problems.

Analogue filters will always be needed for interfacing between digital systems and the 'real' analogue world. In fact, the high frequency integrated analogue filter has become a key component in achieving ubiquitous communication and computing. In recent years, the renewed interest in analogue, mixed-signal and RF circuits due to the need for system-on-chip design and the market for wireless communications has led to a new peak of research into high frequency integrated analogue filters. This book brings together the leading researchers in high frequency analogue filters to highlight recent advances and identify promising directions for future development. Coverage includes Gm-C filters, MOSFET-C filters, active-LC filters, logdomain filters, switched-current filters, adaptive analogue filters and on-chip automatic filter tuning. The topical nature of the book and calibre of the authors ensures that this book will be of great interest to the electronics and communications communities worldwide.

A rich source of information for all actively involved parties, this book analyzes and evaluates developments in nonmilitary, private, and public land mobile communications systems.

The Square Kilometre Array (SKA) radio telescope is set to become the largest telescope on Earth, and also the largest science project in Africa. From September 2011 to August 2012, the SKA featured regularly in the South African media. In The Stars in Our Eyes, author Michael Gastrow dissects the representation of the SKA in the South African media in the period under discussion. Who were the main actors in this unfolding narrative? Who held the stage and who were marginalised? Where did gatekeeping occur and why? What was the relationship between journalists and scientists? How did the story unfold in the social media as opposed to the print media? Drawing on mass communication theory and science communication theory, The Stars in Our Eyes: Representations of the Square kilometre Array Telescope in the South African Media addresses critical gaps in the literature on science communication, particularly with respect to science communication in an African context.

This text offers a comprehensive treatment of the entire GSM network and the signalling methods of its terrestrial interfaces. It introduces all the interfaces between the GSM subsystems, starting with the Abis- and Air-Interface and continuing on to VLRs, HLRs and MSCs within the NSS. The reader learns about the various signalling standards or methods used in GSM, including TCAP and MAP, and how to apply this knowledge when working with GSM networks. The glossary explains abbreviations, terms, parameters, counters and messages frequently encountered when working with GSM. In addition, it features numerous figures, tables, lists, statistical formulas, real-life examples and everyday comparisons.

This book provides a detailed review of power amplifiers, including classes and topologies rarely covered in books, and supplies sufficient information to allow the reader to design an entire amplifier system, and not just the power amplification stage. A central aim is to furnish readers with ideas on how to simplify the design process for a preferred power amplifier stage by introducing software-based routines in a programming language of their choice. The book is in two parts, the first focusing on power amplifier theory and the second on EDA concepts. Readers will gain enough knowledge of RF and microwave transmission theory, principles of active and passive device design and manufacturing, and power amplifier design concepts to allow them to quickly create their own programs, which will help to accelerate the transceiver design process. All circuit designers facing the challenge of designing an RF or microwave power amplifier for frequencies from 2 to 18 GHz will find this book to be a valuable asset.

This book focuses on how to apply network coding at different layers in wireless networks - including MAC, routing, and TCP - with special focus on cognitive radio networks. It discusses how to select parameters in network coding (e.g., coding field, number of packets involved, redundant information ration) in order to be suitable for the varying wireless environments. The author explores how to deploy network coding in MAC to improve network performance and examine joint network coding with opportunistic routing to improve the successful rate of routing. In regards to TCP and network coding, the author considers transport layer protocol working with network coding to overcome the transmission error rate, particularly with how to use the ACK feedback of TCP to enhance the efficiency of network coding. The book pertains to researchers and postgraduate students, especially whose interests are in opportunistic routing and TCP in cognitive radio networks.
