Wireless Transceiver Circuits System Perspectives and Design Aspects

Modern transceiver systems require diversified design aspects as various radio and sensor applications have emerged. Choosing the right architecture and understanding interference and linearity issues are important for multistandard cellular transceivers and software-defined radios. A millimeter-wave CMOS transceiver design for multi-Gb/s data transmission is another challenging area. Energy-efficient shortrange radios for body area networks and sensor networks have recently received great attention. To meet different design requirements, gaining good system perspectives is important. This book addresses not only comprehensive system design considerations for robust wireless communication but also practical design aspects in state-of-the-art transceivers. In addition to dealing with system architectures and design considerations, a few chapters are devoted to critical building blocks with detailed circuit description and analyses.

Introduction to Mobile Network Engineering: GSM, 3G-WCDMA, LTE and the Road to 5G

Concentrating on three mobile communication technologies, GSM, 3G-WCDMA, and LTE—while majorly focusing on Radio Access Network (RAN) technology—this book describes principles of mobile radio technologies that are used in mobile phones and service providers’ infrastructure supporting their operation. It introduces some basic concepts of mobile network engineering used in design and rollout of the mobile network. It then follows up with principles, design constraints, and more advanced insights into radio interface protocol stack, operation, and dimensioning for three major mobile network technologies: Global System Mobile (GSM) and third (3G) and fourth generation (4G) mobile technologies. The concluding sections of the book are concerned with further developments toward next generation of mobile network (5G). Those include some of the major features of 5G such as a New Radio, NG-RAN distributed architecture, and network slicing. The last section describes some key concepts that may bring significant enhancements in future technology and services experienced by customers.

Toward 6G. A New Era of Convergence

Toward 6G: A New Era of Convergence offers an up-to-date guide to the emerging 6G vision by describing new human-centric services made possible by combinations of mobile robots, avatars, and smartphones, which will be increasingly replaced with wearable displays and haptic interfaces that provide immersive extended reality (XR) experiences. The authors―noted experts on the topic―include a review of their work and information on the recent progress on the Tactile Internet and multi-sensory haptic communications. The book highlights decentralized edge computing in particular via Ethereum blockchain technologies, most notably the so-called decentralized autonomous organization (DAO) for crowdsourcing of human skills to solve problems that machines (such as autonomous artificial intelligence agents and robots) alone cannot solve well.

RF and Microwave Engineering. Fundamentals of Wireless Communications

This book provides a fundamental and practical introduction to radio frequency and microwave engineering and physical aspects of wireless communication. In this book, the author addresses a wide range of radio-frequency and microwave topics with emphasis on physical aspects including EM and voltage waves, transmission lines, passive circuits, antennas, radio wave propagation. Up-to-date RF design tools like RF circuit simulation, EM simulation and computerized smith charts, are used in various examples to demonstrate how these methods can be applied effectively in RF engineering practice. Design rules and working examples illustrate the theoretical parts. The examples are close to real world problems, so the reader can directly transfer the methods within the context of their own work. At the end of each chapter a list of problems is given in order to deepen the reader's understanding of the chapter material and practice the new competences. Solutions are available on the author's website

Signals & Systems

This book is the second edition of a text designed for undergraduate courses in signals and systems. While such courses are frequently found in electrical engineering curricula, the concepts and techniques that form the core of the subject are of fundamental importance in all engineering disciplines. In fact, the scope of potential and actual applications of the methods of signal and system analysis continues to expand as engineers are confronted with new challenges involving the synthesis or analysis of complex processes. For these reasons we feel that a course in signals and systems not only is an essential element in an engineering program but also can be one of the most rewarding, exciting, and useful courses that engineering students take during their undergraduate education.

Practical Antenna Handbook

Design and construct your own antennas with step-by-step instructions and plans. Joseph J. Carr's Practical Antenna Handbook, Fourth Edition, is an update of the most popular book on antennas ever written. This empowering guide blends theoretical concepts that engineers need to design practical antennas with hard-learned lessons derived from actually building and using antennas -- real antennas, not merely theoretical constructs on a blackboard. Certain to become the toolbox favorite of radio enthusiasts and professionals of all types, from technicians to citizen banders and shortwave listeners, it covers a wide variety of antennas: high-frequency dipole; vertically polarized HF; multiband and tunable wire; hidden and limited space; directional phased vertical and directional beam VHF/UHF transmitting and receiving; shortwave reception; microwave; and mobile, marine, and emergency. This state-of-the-art edition includes a new chapter on antenna modeling software and new coverage of small transmitting antennas and receiving loop antennas.
