This volumes discusses various aspects regarding the capacity/achievable data rate of stationary Rayleigh fading channels. First, it analyses bounds on the achievable data rate with zero-mean proper Gaussian input symbols, which are capacity achieving in the coherent case, i.e., in case of perfect channel knowledge at the receiver. These bounds are tight in the sense that the difference between the upper and the lower bound is bounded for all SNRs. The lower bound converges to the coherent capacity for asymptotically small channel dynamics. Furthermore, these bounds are extended to the case of multiple-input multiple-output (MIMO) channels and to the case of frequency selective channels. In a further part, the present work studies the achievable rate with receivers based on synchronized detection and a code-aided channel estimation. For a specific type of such a receiver an approximate upper bound on the achievable rate is derived. The comparison of this approximate upper bound and the achievable data rate with receivers using synchronized detection based on a solely pilot based channel estimation gives an approximate upper bound on the possible gain by using this kind of code-aided channel estimation in comparison to the conventional receiver using a solely pilot based channel estimation. In addition, the achievable data rate with an optimal joint processing of pilot and data symbols is studied and a lower bound on the achievable rate for this case is derived. In this context, it is also shown which part of the mutual information of the transmitter and the receiver is discarded when using the conventional receiver with synchronized detection based on a solely pilot based channel estimation.

This book offers an extensive analysis of Woolf's engagement with science. It demonstrates that science is integral to the construction of identity in Woolf's novels of the 1930s and 1940s, and identifies a little-explored source for Woolf's scientific knowledge: BBC scientific radio broadcasts. By analyzing this unstudied primary material, it traces the application of scientific concepts to questions of identity and highlights a single concept that is shared across multiple disciplines in the modernist period: the idea that modern science undermined individualized conceptions of the self. It broadens our understanding of the relationship between modernism and radio, modernism and science, and demonstrates the importance of science to Woolf's later novels.

This book concerns a new paradigm in the field of UHF RFID systems: the positive exploitation of nonlinear signals generated by the chips integrated into the RFID tags. After having recalled the main principles in RFID technology and its current challenges notably with the emergence of Internet of Things or the smart connected environments, the purpose is to focus on the presence of nonlinearities produced by the nonlinear circuits of RFID chips: effects, nuisances and solutions but also and especially use of the phenomena. The presentation covers all aspects from the characterization of the nonlinear behavior of RFID tags and the associated platforms (distinguishing conducted and radiated measurement) to the design of new types of tags where nonlinearities are exploited in order to offer new capabilities or enhanced performance.

This book is open access and available on www.bloomsburycollections.com. It is funded by Knowledge Unlatched. The 20th century was a time of rapid expansion in media industries, as well as of accelerating demands for equality and recognition for women. While women’s agency has typically been defined through the domestic sphere, the introduction of media into the home destabilised firm boundaries between public and private spheres. Gender and Media in the Broadcast Age demonstrates how women as media producers and audiences in three countries with public service broadcasters (UK, Canada and Australia) have contributed to changes in our understandings of public and private. Justine Lloyd offers a new way of understanding how tremendous changes in social definitions of gender roles played out in media forms worldwide during this period through the notion of ‘intimate geographies’. Women’s participation in media continues to be a key challenge to notions of the public sphere and the book concludes that profound changes initiated in the broadcast era are unfinished in the age of digital media. Lloyd therefore provides rich and valuable evidence of the dynamic relationship between media texts, producers and audiences that is relevant to contemporary debates about a growing gender ‘apartheid’ in a mediated culture.

This text covers the analysis and design of all high-frequency oscillators required to realize integrated transceivers for wireless and wired applications. Starting with an in-depth review of basic oscillator theory, the authors provide a detailed analysis of many oscillator types and circuit topologies.

Ultra Wide Band (UWB) technology consists of transmitting radio signals over frequency bandwidths from 500 MHz to several GHz. Its unique characteristics may be exploited for the design of high data rate wireless communication systems, as well as localization and imaging applications. The development and optimization of such systems require a precise knowledge of the radio transmission medium. This book examines all aspects of the propagation channel for UWB systems. UWB technology is first presented, with a particular emphasis being placed on its applications, spectrum regulation issues, and the different communication techniques. The authors introduce the theoretical bases of radioelectric propagation and give an overview of the channel sounding techniques adapted for UWB signals. The two main principles of UWB channel modeling are finally exposed and illustrated: deterministic channel modeling, based on the simulation of the propagation phenomena in a given environment, and statistical channel modeling, which relies on the experimental analysis of the main channel characteristics.

The considerable growth of RFID is currently accompanied by the development of numerous identification technologies that complement those already available while seeking to answer new problems. Chipless RFID is one example. The goal is to both significantly reduce the price of the tag and increase the amount of information it contains, in order to compete with the barcode while retaining the benefits of a flexible reading approach based on radio communication. To solve the problem of the number of bits, this book describes the possibility of coding the information at the level of the overall shape of the RCS of the tag, which would facilitate reaching very large quantities. The design of the tags then returns to the resolution of the inverse problem of the electromagnetic signature. The proposed design methodology regularizes the problem by decomposing the signature on a basis of elementary patterns whose signature is chosen in advance.

Two new fields have recently appeared: mobile ad hoc networks and sensor networks. The emergence of these very promising systems is mainly due to great technological progress in the field of wireless communication protocols; these will make it possible to offer a broad range of new applications in both civilian and militarian domains. The inherent characteristics of these systems imply new challenges. This book deals with several relevant fields related to the evolution of these spontaneous and self-organized networks.The authors tackle critical problems such as the design of unicast/multicast routing protocols, the support of the quality of service, the security mechanisms for routing and data transmission, the service discovery, the techniques of clustering/self-organization, the mobility of code and the fault-tolerance techniques. The discussion adopts an analysis-oriented approach which aims to cover the current cutting-edge aspects of these fields and to highlight some potential future development, making it essential reading for anyone wishing to gain a better understanding of these exciting new areas.

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. This book will be warmly welcomed by scholars of astronomy, atmospheric science, geoscience, military and institutional history, and the history and philosophy of science and technology, as well as by radio amateurs and electrical engineers interested in historical perspectives on their craft.

UMTS is not about technology, it's about Services...

The UMTS (Universal Mobile Telecommunications System) or 3G (3rd Generation mobile networks) environment is the ultimate convergence of fixed and mobile, voice and data, content and delivery. The result is the largest, and most complex communications system that man has designed. The industry is expected to generate revenues in excess of a trillion dollars in less than ten years. If you want a challenge, then this is the industry to be in.

Services for UMTS is about the near future, where UMTS allows mobile phones and other devices for communications, entertainment, personalised services, utility and fun to be used in new ways.

While it is difficult to predict the future in a precise way, broad categories and general service ideas are emerging. This volume looks at over 200 of these possible applications and provides more detailed scenarios on over 170 of them. It explores these ideas in depth, with suggestions on how to create exciting and viable services for a new world.

Written for the non-technical reader and with a strong business focus, Services for UMTS is a "must-read" for anybody wanting to enter the UMTS environment, to understand it, or to make money in it.

Services for UMTS intends to answer many of the current UMTS service questions as well as introduce new ideas and concepts to enable operators to create a winning UMTS services strategy.

• What should be the focus of service creation for rapid profits in UMTS

• What are the key segments that should be addressed with UMTS services

• What are the roles of the network operator, service provider, application developer, system integrator, and others in partnership

• How to build more value into digital services to turn them into killer applications for their target segments

• What are the differentiating factors that will separate the leaders from the UMTS pack

• How the new Mobile Internet differs from the existing fixed Internet, and why users, content and revenues will migrate to the Mobile Internet

• The 5 M's of creating desirable and profitable UMTS service

We are currently witnessing an increase in telecommunications norms and standards given the recent advances in this field. The increasing number of normalized standards paves the way for an increase in the range of services available for each consumer. Moreover, the majority of available radio frequencies have already been allocated. This explains the emergence of cognitive radio (CR) - the sharing of the spectrum between a primary user and a secondary user. In this book, we will present the state of the art of the different techniques for spectrum access using cooperation and competition to solve the problem of spectrum allocation and ensure better management of radio resources in a radio cognitive context. The different aspects of research explored up until now on the applications of multi-agent systems (MAS) in the field of cognitive radio are analyzed in this book. The first chapter begins with an insight into wireless networks and mobiles, with special focus on the IEEE 802.22 norm, which is a norm dedicated to CR. Chapter 2 goes into detail about CR, which is a technical field at the boundary between telecommunications and Artificial Intelligence (AI). In Chapter 3, the concept of the "agent" from AI is expanded to MAS and associated applications. Finally, Chapter 4 establishes an overview of the use of AI techniques, in particular MAS, for its allocation of radio resources and dynamic access to the spectrum in CR.

The standards GPRS and EDGE significantly enhance the GSM standard for mobile communications by supporting packet-oriented data services with higher bit rates than currently possible. This enables transparent access to fixed packet data networks. While GPRS will provide data services prior to UMTS deployment, both GPRS and EDGE have the potential to complement 3G networks. Initially UMTS will only be available in areas with high subscriber density. With the availability of multi-mode terminals supporting both UMTS and GPRS/EDGE (GERAN), data services will be supported outside the UMTS coverage area by both GPRS and EDGE. Therefore packet data services based on GERAN are expected to play an important role in mobile communications far beyond 2010.
