This book explores some of the technological challenges in the application of digital communications technology in the home, including provision of fast, 'always on' internet connections. It looks at the ways consumers will use broadband access and what the key applications will be for provider and consumer. More broadly it aims to describe how communication to and within the home is evolving, and how people's lives are changing as they take advantage of the new technology and its applications. The expert contributors consider delivery mechanisms for broadband, connecting the home to external networks as well as connecting devices and applications within the home. They discuss how people use and relate to the technology, and how it should be developed to meet their evolving needs. Current applications are described and how new applications are being developed to take advantage of new digital technology. Finally two visionaries give their insights into aspects of the future for the home environment and how much it will be a digital home. This fascinating book provides balanced coverage of the issues surrounding this next phase of the development of communications and the Internet, which may transform our homes and the way we live. It will be of major interest to engineers and other professionals working in communications, IT, new technology and entertainment, as well as those active in research within a number of fields of technology.
The market for consumer electronics is characterized by rapidly growing complexities of applications and decreasing market window opportunities. A key concept for coping with such requirements is the reuse of system components. Embedding programmable processors into VLSI systems facilitates reuse and offers a high degree of flexibility. The use of embedded processors, however, poses challenges for software compilers, because real-time constraints and limited silicon area for program memories demand extremely efficient machine code. Additionally there is a need for flexible, retargetable compilers which explore the mutual dependence between processor architectures and program execution speed. Current compiler technology does not meet these demands, particularly the area of DSP where application-specific processors are predominant. As a consequence, the largest part of DSP software is still developed manually at assembly language level. Recent research efforts, located at the intersection of software and hardware design, aim at eliminating this bottleneck. Retargetable Code Generation for Digital Signal Processors outlines the new role of compilers in hardware/software codesign of embedded systems, and it describes the state-of-the-art in the area of retargetable code generation and optimization for embedded DSPs. It presents novel concepts and algorithmic solutions, which achieve both retargetability and high code quality. In contrast to approaches taken in classical compiler construction, emphasis is put on effective code optimization instead of high compilation speed. The usefulness of the proposed techniques is demonstrated for real-life architectures. Retargetable Code Generation forDigital Signal Processors, with a foreword by Peter Marwedel, is the first contribution to this area, that presents an integrated solution for retargetable DSP compilers. It covers the whole compilation process, including target processor modelling, intermediate code generation, code selection, register allocation, scheduling and optimization for parallelism. It will be of interest to researchers, senior design engineers and CAD managers both in academia and industry.
This book is for designers and would-be designers of digital communication systems. The general approach of this book is to extract the common principles underlying a range of media and applications and present them in a unified framework. Digital Communication is relevant to the design of a variety of systems, including voice and video digital cellular telephone, digital CATV distribution, wireless LANs, digital subscriber loop, metallic Ethernet, voiceband data modems, and satellite communication systems. New in this Third Edition: New material on recent advances in wireless communications, error-control coding, and multi-user communications has been added. As a result, two new chapters have been added, one on the theory of MIMO channels, and the other on diversity techniques for mitigating fading. Error-control coding has been rewritten to reflect the current state of the art. Chapters 6 through 9 from the Second Edition have been reorganized and streamlined to highlight pulse-amplitude modulation, becoming the new Chapters 5 through 7. Readability is increased by relegating many of the more detailed derivations to appendices and exercise solutions, both of which are included in the book. Exercises, problems, and solutions have been revised and expanded. Three chapters from the previous edition have been moved to the booka (TM)s Web site to make room for new material. This book is ideal as a first-year graduate textbook, and is essential to many industry professionals. The book is attractive to both audiences through the inclusion of many practical examples and a practical flavor in the choice of topics. Digital Communicationhas a Web site at: http: //www.ece.gatech.edu/~barry/digital/, where the reader may find additional information from the Second Edition, other supplementary materials, useful links, a problem solutions manual, and errata.
Shows how to combine physical optics modelling techniques with the free space dyadic Green's function to quickly calculate antenna patterns and diffraction from nearby objects. This work also shows how to apply basic routines to focus more time on the actual solution of antenna radiation problems.
This textbook presents a practical introduction to information security using the Competency Based Education (CBE) method of teaching. The content and ancillary assessment methods explicitly measure student progress in the three core categories: Knowledge, Skills, and Experience, giving students a balance between background knowledge, context, and skills they can put to work. Students will learn both the foundations and applications of information systems security; safeguarding from malicious attacks, threats, and vulnerabilities; auditing, testing, and monitoring; risk, response, and recovery; networks and telecommunications security; source code security; information security standards; and compliance laws. The book can be used in introductory courses in security (information, cyber, network or computer security), including classes that don't specifically use the CBE method, as instructors can adjust methods and ancillaries based on their own preferences. The book content is also aligned with the Cybersecurity Competency Model, proposed by department of homeland security. The author is an active member of The National Initiative for Cybersecurity Education (NICE), which is led by the National Institute of Standards and Technology (NIST). NICE is a partnership between government, academia, and the private sector focused on cybersecurity education, training, and workforce development.

The book presents current research, directed to securing supply chains against the efforts of counterfeit operators, carried out at the Auto-ID Labs around the globe. It assumes very little knowledge on the part of the reader on Networked RFID systems as the material provided in the introduction familiarizes the reader with concepts, underlying principles and vulnerabilities of modern RFID systems.
Every endeavour is covered by some fault, just as ?re is covered by smoke. Therefore one should not give up the work born of his nature, even if such work is full of fault. - The Bhagvad-Gita (18.48) This book is the outcome of the research and developmentcontributions of partners from three different continents, Asia, Europe, America, coming from universities, research centers, industrial partners and SMEs (Small and Medium Enterprise), all of them collaborating in MAGNET (My Adaptive Personal Global Net) and MAGNET Beyond project supported by European Commission within the Sixth Framework Programme (FP6). The project was focusing on a secure user-centric approach developingsecure Personal Networks in multi-network, multi-device, and multi-user environments. The innovative concept of Personal Network (PN), which was introduced and developed in MAGNET, ?nds in this book the ?rst con?rmation of the success that the future of wireless communications is bound to achieve. The importance of this book is not only related to being the ?rst work on PNs, it also gives an overview of operation of a big project, like MAGNET, and in fact the organisation of the book re?ects how then project itself has been structured
Telecommunications today is in the midst of far-reaching changes due to rapid development of new technologies, services and social evolution. This is the first book to model the process of change in telecommunications, including all of the relevant factors. The approach is practical and responsible, based on hard facts and tested models. It deals with fundamental issues affecting the future development of telecoms and its impact on societies and presents views which some will find radical.
The book describes a method for creating models of telecom systems. The method is intended for practitioning network architects and designers. The method emphasizes modelling the (very complex) functional structure of networks in a way that is independent of any hardware and software design methodology. The method allows designers to express their model in two main views: a generic view and a system view that takes protocols and network configuration issues in account. The idea is to retain a stable view (the generic) in the context of constant changes and large variations within the system view. The expected benefits are large savings in telecom systems development and maintenance. The terminology is domain unique, i.e. based on de-facto telecom terminology. All concepts that are used in modelling are well defined. The purpose with using a telecom-oriented terminology instead of industry-standard methods for software and protocol design (e.g. UML and SDL) is to be able to create models that are expressive and intelligible for network architects and designers. Models are created as graphical models that show the functional and physical structure of networks on different levels of details. Information on properties, including behaviour, are attached to models. A fairly small set of symbols are used in modelling.
All-optical networking is generally believed to be the only
solution for coping with the ever-increasing demands in bandwidth,
such as the World Wide Web application.
"Optimal Design of Distributed Control and Embedded Systems "focuses on the design of special control and scheduling algorithms based on system structural properties as well as on analysis of the influence of induced time-delay on systems performances. It treats the optimal design of distributed and embedded control systems (DCESs) with respect to communication and calculation-resource constraints, quantization aspects, and potential time-delays induced by the associated communication and calculation model. Particular emphasis is put on optimal control signal scheduling based on the system state. In order to render this complex optimization problem feasible in real time, a time decomposition is based on periodicity induced by the static scheduling is operated. The authors present a co-design approach which subsumes the synthesis of the optimal control laws and the generation of an optimal schedule of control signals on real-time networks as well as the execution of control tasks on a single processor. The authors also operate a control structure modification or a control switching based on a thorough analysis of the influence of the induced time-delay system influence on stability and system performance in order to optimize DCES performance in case of calculation and communication resource limitations. Although the richness and variety of classes of DCES preclude a completely comprehensive treatment or a single best method of approaching them all, this co-design approach has the best chance of rendering this problem feasible and finding the optimal or some sub-optimal solution. The text is rounded out with references to such applications as car suspension and unmanned vehicles. "Optimal Design of Distributed Control and Embedded Systems" will be of most interest to academic researchers working on the mathematical theory of DCES but the wide range of environments in which they are used also promotes the relevance of the text for control practitioners working in the avionics, automotive, energy-production, space exploration and many other industries."
The RF front-end - antenna combination is a vital part of a mobile phone because its performance is very relevant to the link quality between hand-set and cellular network base-stations. The RF front-end performance suffers from changes in operating environment, like hand-effects, that are often unpredictable. Adaptive RF Front-Ends for Hand-Held Applications presents an analysis on the impact of fluctuating environmental parameters. In order to overcome undesired behavior two different adaptive control methods are treated that make RF frond-ends more resilient: adaptive impedance control, and adaptive power control. Several adaptive impedance control techniques are discussed, using a priori knowledge on matching network properties, in order to simplify robust 2-dimensional control. A generic protection concept is presented, based on adaptive power control, which improves the ruggedness of a power amplifier or preserves its linearity under extremes. It comprises over-voltage, over-temperature, and under-voltage protection.
Magnetic data storage can be viewed as a data communication system. This is not a sUlprising view, considering that data storage is essentially the transfer of data between different times. The past decade has indeed seen rapidly growing interest in applying improved coding and detection techniques to magnetic data storage, a traditional approach to enhance performance of communication channels. Since its inception in the 1930's, the magnetic recording industry has achieved impressive progress in data capacity. This has been made possible mainly by innovations and advances in heads and media design. However, as the demand for higher storage capacity continues in the modem information era, a need arises to explore other possibilities to help meet the ever-growing demand. Advanced coding and detection are one such possibility, providing an efficient, cost-effective means to increase data capacity. In fact, with the advent of modem Ie technology which has enabled real-time implementation of increasingly complex signal processing algorithms, advanced coding and detection are rapidly becoming a major issue in the development of improved data storage products. While there have been remarkable advances in recent years in the areas of both coding and detection for data storage, this book focuses only on data detection, or the processing of readback waveforms to reproduce stored data, in conjunction with the traditional modulation coding method called run length-limited or (d, k) coding."
This book is the result of the contributions coming from the more than thirty key rd speakers of the 3 international Workshop on Nonlinear Microwave Magnetics held in th Roma, Italy from the 3rd to the 6 of October 1995. Since the 1990, in Ulyanovsk, when the Russian Academy of Sciences promoted the first Workshop of the series, the basic idea was to have a sort of Institutional Meeting collecting Scientists of the Magnetics Community devoted to Spin Wave Electronics at Microwave Frequencies. It was a succesful organization, and the birth of an effective interaction between eastern and western researchers overcame the meaning of the Workshop itself. Three years later, in Irvine, California, 1993, the Spin Wave Community was joined again. It was clear that the growing interest on hot topics of Nonlinear Microwave Magnetics involving both, applicative and fundamental aspects of microwave magnetic media, favoured the organization of further meetings on the same subject. So far, during the social dinner, in the middle between a serious proposal and the joke encouraged by the Californian Wine, Roma was proposed as the third place for the Workshop. Day after day, the joke became serious, and it was possible to solve the financial and logistic problems in time for the predicted deadline.
Covering some of the most cutting-edge research on the delivery and retrieval of interactive multimedia content, this volume of specially chosen contributions provides the most updated perspective on one of the hottest contemporary topics. The material represents extended versions of papers presented at the 11th International Workshop on Image Analysis for Multimedia Interactive Services, a vital international forum on this fast-moving field. Logically organized in discrete sections that approach the subject from its various angles, the content deals in turn with content analysis, motion and activity analysis, high-level descriptors and video retrieval, 3-D and multi-view, and multimedia delivery. The chapters cover the finest detail of emerging techniques such as the use of high-level audio information in improving scene segmentation and the use of subjective logic for forensic visual surveillance. On content delivery, the book examines both images and video, focusing on key subjects including an efficient pre-fetching strategy for JPEG 2000 image sequences. Further contributions look at new methodologies for simultaneous block reconstruction and provide a trellis-based algorithm for faster motion-vector decision making.
Principles of Digital Transmission is designed for advanced undergraduate and graduate level students and professions in telecommunications. Teachers and learners can mix and match chapters to create four distinct courses: (1) a one-term basic course in digital communications; (2) a one-term course in advanced digital communications; (3) a one-term course in information theory and coding; (4) a two-term course sequence in digital communications and coding. The book provides rigorous mathematical tools for the analysis and design of digital transmission systems. The authors emphasize methodology in their aim to teach the reader how to do it rather than how it is done. They apply the fundamental tools of the discipline onto a number of systems, such as wireless data transmission systems.
This book takes a pragmatic approach to deploying state-of-the-art optical networking equipment in metro-core and backbone networks. The book is oriented towards practical implementation of optical network design. Algorithms and methodologies related to routing, regeneration, wavelength assignment, sub rate-traffic grooming and protection are presented, with an emphasis on optical-bypass-enabled (or all-optical) networks. The author has emphasized the economics of optical networking, with a full chapter of economic studies that offer guidelines as to when and how optical-bypass technology should be deployed. This new edition contains: new chapter on dynamic optical networking and a new chapter on flexible/elastic optical networks. Expanded coverage of new physical-layer technology (e.g., coherent detection) and its impact on network design and enhanced coverage of ROADM architectures and properties, including colorless, directionless, contentionless and gridless. Covers 'hot' topics, such as Software Defined Networking and energy efficiency, algorithmic advancements and techniques, especially in the area of impairment-aware routing and wavelength assignment. Provides more illustrative examples of concepts are provided, using three reference networks (the topology files for the networks are provided on a web site, for further studies by the reader). Also exercises have been added at the end of the chapters to enhance the book's utility as a course textbook.
Fractional processes are widely found in science, technology and engineering systems. In Fractional Processes and Fractional-order Signal Processing, some complex random signals, characterized by the presence of a heavy-tailed distribution or non-negligible dependence between distant observations (local and long memory), are introduced and examined from the 'fractional' perspective using simulation, fractional-order modeling and filtering and realization of fractional-order systems. These fractional-order signal processing (FOSP) techniques are based on fractional calculus, the fractional Fourier transform and fractional lower-order moments. Fractional Processes and Fractional-order Signal Processing: presents fractional processes of fixed, variable and distributed order studied as the output of fractional-order differential systems; introduces FOSP techniques and the fractional signals and fractional systems point of view; details real-world-application examples of FOSP techniques to demonstrate their utility; and provides important background material on Mittag-Leffler functions, the use of numerical inverse Laplace transform algorithms and supporting MATLAB (R) codes together with a helpful survey of relevant webpages. Readers will be able to use the techniques presented to re-examine their signals and signal-processing methods. This text offers an extended toolbox for complex signals from diverse fields in science and engineering. It will give academic researchers and practitioners a novel insight into the complex random signals characterized by fractional properties, and some powerful tools to analyze those signals.
