Written by two leading experts in the field, this exceptional book introduces the reader to the principles, theory and applications of physical layer wireless/mobile communications. In the area of wireless, the antennas, propagation and the radio channel used are inter-related; this book offers an explanation of that relationship, which is fundamental to the development of systems with high spectral efficiency. Channels, Propagation and Antennas for Mobile Communications emphasises the basic principles needed to establish an understanding of this technology. However, the tools required - such as the mathematics and statistics - are treated in the manner of a practical handbook, avoiding detailed derivations. The reader will develop a clear insight into the physics and effects of multipath and the use of multipath channels for communications. Propagation modelling, simulation and measurement, scattering, antenna principles, array antennas, adaptive antennas and smart antennas are also covered. This book will be a valuable reference for senior undergraduates and postgraduates in electrical engineering and communications. Practising design engineers, systems designers and engineering managers will also gain a sound understanding of the field.

Vast numbers of radio systems are now in use, and with new users and new uses constantly emerging, these systems have the potential to interfere with each other. National agencies are empowered to control the use of radio to ensure that systems within their jurisdiction do not disrupt each other's services. Interference may also arise between radio systems operating in different countries. An elaborate code of regulations has been agreed, under the aegis of the International Telecommunication Union, to facilitate cooperation between the national agencies to control interference across frontiers. The Union also provides the global forum for the standardisation of radio systems where this has been found to be desirable. For some kinds of radio system, especially broadcasting and land mobile radio, governments may also find it necessary to determine which of the organisations competing to provide radio facilities for public use should be licensed and which should not. This process is known as regulation. Intended as a handbook for administrators and engineers, this book reviews the processes of interference management, regulation of competing service providers and system standardisation for the control and use of the radio spectrum. At a time when telecommunication services and broadcasting are being liberalised in many countries, this book will also provide new operators of radio facilities, private and public, with valuable insights into the regulatory process.

This topical book builds upon an earlier IEE text Personal & mobile radio systems, by the same editor, which set out the fundamental issues in a discipline that appeared to have global expansion potential. That potential has now become a reality, and something more than a new edition of the previous book was needed to bring it up to date. This book is completely new, drawing on the experience and the many intensive studies that have been concentrated in this field in the past five years. The book gives a clear and detailed insight into the fundamental problems and solutions found in modern personal communications: service requirements, coverage problems, multipath interference, cellular architectures and signalling, network management, data and supplementary services, satellite services. In particular it describes the approach of the GSM methodology, as one of the most intensively developed standards, to some of these problems, although the same principles also apply to DCS 1800 and other technologies.

Much has been written about Faraday and Marconi, and about the history of the development of radio from the time of Marconi. However, Gerald Garratt's special interest was in what might be termed the 'prehistory' of radio. This book therefore outlines the sequence of development from Faraday's first prediction and concept of the electromagnetic field: Maxwell worked out the mathematics of electromagnetic wave propagation and Hertz demonstrated their physical existence. Lodge identified the need for resonance between transmitter and receiver, thus leading to Marconi's successful practical application.

Including coverage of primary sources and current research trends, this is essential reading for researchers, practitioners and graduate students working on vacuum electron devices.
By the late nineteenth century, engineers and experimental scientists generally knew how radio waves behaved, and by 1901 scientists were able to manipulate them to transmit messages across long distances. What no one could understand, however, was why radio waves followed the curvature of the Earth. Theorists puzzled over this for nearly twenty years before physicists confirmed the zig-zag theory, a solution that led to the discovery of a layer in the Earth's upper atmosphere that bounces radio waves earthward-the ionosphere. In Probing the Sky with Radio Waves, Chen-Pang Yeang documents this monumental discovery and the advances in radio ionospheric propagation research that occurred in its aftermath. Yeang illustrates how the discovery of the ionosphere transformed atmospheric science from what had been primarily an observational endeavor into an experimental science. It also gave researchers a host of new theories, experiments, and instruments with which to better understand the atmosphere's constitution, the origin of atmospheric electricity, and how the sun and geomagnetism shape the Earth's atmosphere.
Adaptive WCDMA covers the latest theoretical principals and practice of wideband code division multiple access (WCDMA), which is the basis for the physical layer of the third generation mobile communications systems. The focus of this volume is on implementation losses characterising the system degradation due to imperfect implementation and in turn how much of the performance promised by theory should be expected in practical solutions based on a given technology, which is not perfect but has finite cost and power consumption. It also provides a significant amount of material related to the further developments and improvements (beyond 3G) especially sections on adaptive WCDMA and modifications for implementations in ad hoc networks. Based on the author’s experience in research and teaching courses in the field at both university and industry, this volume provides a simultaneous account of the theoretical principles of the technology and how and why these principles are used in the standards. Written in an accessible and simple to read style the book serves as both an introductory level text and as a more advanced reference. It has a step by step approach which introduces the theory and the standard to those new to the topic yet will meet the expectations of readers from varying backgrounds and levels. Topics covered include:
Over the past two decades we have witnessed the increasing popularity of the internet of things. The vision of billions of connected objects, able to interact with their environment, is the key driver directing the development of future communication devices. Today, power consumption as well as the cost and size of radios remain some of the key obstacles towards fulfilling this vision. Ultra-Low Power FM-UWB Transceivers for IoT presents the latest developments in the field of low power wireless communication. It promotes the FM-UWB modulation scheme as a candidate for short range communication in different IoT scenarios. The FM-UWB has the potential to provide exactly what is missing today. This spread spectrum technique enables significant reduction in transceiver complexity, making it smaller, cheaper and more energy efficient than most alternative options. The book provides an overview of both circuit-level and architectural techniques used in low power radio design, with a comprehensive study of state-of-the-art examples. It summarizes key theoretical aspects of FM-UWB with a glimpse at potential future research directions. Finally, it gives an insight into a full FM-UWB transceiver design, from system level specifications down to transistor level design, demonstrating the modern power reduction circuit techniques. Ultra-Low Power FM-UWB Transceivers for IoT is a perfect text and reference for engineers working in RF IC design and wireless communication, as well as academic staff and graduate students engaged in low power communication systems research.
