Personal and Wireless Communications: Digital Technology and Standards is devoted to providing a concise explanation of the newly emerging wireless access standards for Personal Communications Services (PCS). PCS is a new concept which will expand the horizon of wireless communications beyond the limitations of current cellular systems to provide end users with the ability to communicate with anyone, anywhere, anytime'. Because of the inherent nature of mobility, which is characteristic of personal communications, wireless communications and PCS have become inseparable concepts. In particular, PCS will critically depend on wireless technologies for the mobile-to-network access portion of the service, which is referred to as the common air interface. The topic of this book is the wireless access technology used for the common air interface in order to support PCS. Personal and Wireless Communications: Digital Technology and Standards presents clear tutorial expositions of the main digital technology elements employed for wireless access systems. The main objective is to pull together in one place all the important basic technical elements necessary in understanding wireless access systems, so that the reader can obtain an overall view of the technology quickly and systematically. The book also reviews the common air interface standards for PCS, and in doing so has two main objectives. The first is to sift out and summarize important elements of the standards, which are buried in the veritable mountain of paper comprising the standards literature, in all too many unfamiliar terms, notations, and abbreviations. The second objective is to expand, almost paradoxically, some of the more important elements to explain the intent and significance of the written words of the standards. Personal and Wireless Communications: Digital Technology and Standards will provide a quick means of obtaining a comprehensive picture of overall aspects which are important in the area. This book will be useful as a text for an advanced course on the subject.

This book fills an information gap on cognitive radios, since the discussion focuses on the implementation issues that are unique to cognitive radios and how to solve them at both the architecture and circuit levels. This is the first book to describe in detail cognitive radio systems, as well as the circuit implementation and architectures required to implement such systems. Throughout the book, requirements and constraints imposed by cognitive radio systems are emphasized when discussing the circuit implementation details. This is a valuable reference for anybody with background in analog and radio frequency (RF) integrated circuit design, needing to learn more about integrated circuits requirements and implementation for cognitive radio systems.

RF Power Amplifiers for Mobile Communications fits in the quest for fully integrated CMOS transceivers. The book tackles both high efficiency and high linearity PA design in low-voltage CMOS, and has a strong emphasis on theory, design and implementation. The book is conceived as a design guide for those actively involved in the design of CMOS wireless transceivers. RF Power Amplifiers for Mobile Communications starts from the basic theory of power amplification from the viewpoint of CMOS integration. The design of switching RF power amplifiers in CMOS is explored and CMOS PA design at low supply voltage using parallel amplification is discussed. Combining both efficiency and linearity is one of the major issues in CMOS PA design for wireless and mobile communications and is subsequently tackled. Different linearization techniques and approaches are discussed and polar modulation is clarified in greater detail.

Due to the explosive global growth in the number of mobile subscribers, as well as the growth predicted in the mobile data segment, the need for improved spectrum efficiency on the radio interface becomes more and more important. Frequency hopping (FH) is an effective method for improving the spectrum efficiency. One of the advantages of FH is that it can be combined with other spectral efficiency improving features like power control, handover and reuse partitioning. Performance Enhancements in a Frequency Hopping GSM Network covers FH and some of the additional features in detail. It begins with an in-depth description of the basic concept of FH on link level as well as on system level. Different methods have been used for analysis, such as link level simulations, network level simulations and classic tele-traffic theory. Special features of Performance Enhancements in a Frequency Hopping GSM Network Combines the practical experiences of operator and vendor with more theoretical research methods. An in-depth treatment of prevailing problems in GSM networks; Presentation of a new method, computer-aided network design (CAND), which has been developed to analyse the complex network structures of a GSM network. CAND provides the possibility for more realistic performance evaluations than conventional methods; Provides GSM-specific analysis of functionality improvements in power control, discontinuous transmission, and several handover algorithms; Explanation of the quality and capacity gains of features like the combination of FH and reuse partitioning, referred to as intelligent frequency hopping; A frequency planning method for FH GSM networks is presented. This method exploits the benefits from FH directly in the allocation process, increasing the overall frequency plan.

Presenting a description of automated HF communications, this work also considers the many phenomena which affect HF radio, and offers insight into new and future HF techniques. It includes information on automatic link establishment (ALE) technology, advanced variable-transmission rate modems, wideband (1 MHz) HF communications services, and automated HF networks as an extension of the Internet.

This book provides an in-depth introduction to the International Telecommunication Union (ITU) Radio Regulations (RR) and the policies that govern them. Established in 1906, these regulations define the allocation of different frequency bands to different radio services, the mandatory technical parameters to be observed by radio stations, especially transmitters, and the procedures for spectrum use coordination at the international level. The book analyzes the interactions between different national policies and the ITU RR, noting how these interactions influence spectrum policy on the national level, setting up a comparative framework within which to view these regulations and their effects. Beginning with an overview of the history of the origins ITU RR, the book takes a deep dive into the components of spectrum management including radio communication service allocation, wireless technology selection, radio usage rights, and spectrum rights assignment, placing each analysis within the context of the push and pull between national and international regulations. The book concludes with chapters discussing issues affecting the future of spectrum policy, including spectrum policy reform in developing countries, the WRC-19, and IMT-2020. Shedding light on the longest-running treaty documents in the history of modern telecommunications and arguing for reforms that allow it to address the needs of all nations, this book is useful to scholars and students of telecom policy, digital policy, ICT, governance, and development as well as telecom industry practitioners and regulators.

Green Software De?ned Radios, the title of this book may have originated from a lackofinspiration, andthecombinationofhardwork, jetlag, anddrinkinggreentea. The message we want to convey however, is that SDRs are a promising technology for the future, providing they are designed for ef?cient usage of scarce resources: energy and spectrum. In the last years, the R&D teams focusing on wireless c- munication (around the world and at IMEC speci?cally), have realized great bre- throughs. It is our honor, building on this knowledge, to bring a comprehensive overview of the essential technologies. We are grateful that Springer is willing to publish in their collection on radio technologies, a book on green SDRs, a weird species still today, yet maybe the baseline for the day after tomorrow. Dear reader, we wish that you ?nd in the following pages, including the references, some int- esting insights, and that this book may live more or less up to your expectations (and hopefully more than less). Thisbook'sclosingstatesthatthequestforGreenSDRshasnotended, thisisjust the beginning. Concerning this book however, we are happy that today the opposite is true. We want to acknowledge our colleagues at IMEC for their great scienti?c contribution, and even more for the enjoyable cooperation.

Growth of wireless communications is demanding increased system capacity for mobile communications satellites - digital beamforming technology provides a promising cost-effective solution to this problem. This text discusses beamforming techniques and results, state-of-the-art supportive technologies and promising applications for wireless communications.

The past several years have been exciting for wireless communications. The public appetite for new services and equipment continues to grow. The Second Generation systems that have absorbed our attention during recent years will soon be commercial realities. In addition to these standard systems, we see an explosion of technical alternatives for meeting the demand for wireless communications. The debates about competing solutions to the same problem are a sign of the scientific and technical immaturity of our field. Here we have an application in search of technology rather than the reverse. This is a rare event in the information business. Happily, there is a growing awareness that we can act now to prevent the technology shortage from becoming more acute at the end of this decade. By then, market size and user expectations will surpass the capabilities of today's emerging systems. Third Generation Wireless Information Networks will place even greater burdens on technology than their ancestors. To discuss these issues, Rutgers University WINLAB plays host to a series of Workshops on Third Generation Wireless Information Networks. The first one, in 1989, had the flavor of a gathering of committed enthusiasts of an interesting niche of telephony. Presentations and discussions centered on the problems of existing cellular systems and technical alternatives to alleviating them. Although the more distant future was the announced theme of the Workshop, it drew only a fraction of our attention.
