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."

The unprecedented growth in the range of multimedia services offered these days by modern telecommunication systems has been made possible only because of the advancements in signal processing technologies and algorithms. In the area of telecommunications, application of signal processing allows for new generations of systems to achieve performance close to theoretical limits, while in the area of multimedia, signal processing the underlying technology making possible realization of such applications that not so long ago were considered just a science fiction or were not even dreamed about. We all learnt to adopt those achievements very quickly, but often the research enabling their introduction takes many years and a lot of efforts. This book presents a group of invited contributions, some of which have been based on the papers presented at the International Symposium on DSP for Communication Systems held in Coolangatta on the Gold Coast, Australia, in December 2003. Part 1 of the book deals with applications of signal processing to transform what we hear or see to the form that is most suitable for transmission or storage for a future retrieval. The first three chapters in this part are devoted to processing of speech and other audio signals. The next two chapters consider image coding and compression, while the last chapter of this part describes classification of video sequences in the MPEG domain.

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.
Optical backbone networks efficiently achieve a high level of traffic aggregation by multiplexing numerous users on circuit-switched wavelength paths - the so-called wavelength routing approach. In contrast, the reduced level of traffic aggregation in access and metro networks makes wavelength routing solutions not adequate. In these network areas, packet-interleaved optical time-division multiplexing with its finer and more dynamic bandwidth allocation is advocated.
The book presents such an approach, known as photonic slot routing. It illustrates how this approach may provide a cost-effective solution to deploying all-optical transport networks, using today's optical device technology. To that end, the author combines DWDM-technology with fixed slot optical switching, and gives a comprehensive description of this approach in which slots are aligned across the wavelengths to form groups of data-flows that propagate as a whole inside the network. Operating algorithms are developed, and network performance is analyzed, both by means of theoretical analysis and many simulations of sample networks.
This work will be of particular interest to researchers and professionals who are active in photonic networking.

Visual Communication: An Information Theory Approach presents an entirely new look at the assessment and optimization of visual communication channels, such as are employed for telephotography and television. The electro-optical design of image gathering and display devices, and the digital processing for image coding and restoration, have remained independent disciplines which follow distinctly separate traditions; yet the performance of visual communication channels cannot be optimized just by cascading image-gathering devices, image-coding processors, and image-restoration algorithms as the three obligatory, but independent, elements of a modern system. Instead, to produce the best possible picture at the lowest data rate', it is necessary to jointly optimize image gathering, coding, and restoration. Although the mathematical development in Visual Communication: An Information Theory Approach is firmly rooted in familiar concepts of communication theory, it leads to formulations that are significantly different from those that are found in the traditional literature on either rate distortion theory or digital image processing. For example, the Wiener filter, which is perhaps the most common image restoration algorithm in the traditional digital image processing literature, fails to fully account for the constraints of image gathering and display. As demonstrated in the book, digitally restored images improve in sharpness and clarity when these constraints are properly accounted for. Visual Communication: An Information Theory Approach is unique in its extension of modern communication theory to the end-to-end assessment of visual communication. from scene to observer. As such, itties together the traditional textbook literature on electro-optical design and digital image processing. This book serves as an invaluable reference for image processing and electro-optical system design professionals and may be used as a text for advanced courses on the subject.

This book presents link-layer cooperative frameworks to improve transmission reliability and network throughput of distributed TDMA MAC protocols in vehicular ad hoc networks (VANETs). The main objective of this book is to present link-layer node cooperation schemes to enhance the link-layer performance of vehicular networks, in terms of reliability and system throughput. The authors present approaches proposed for the medium access control (MAC) and node cooperation in VANETs. The authors also cover cooperative ADHOC MAC for point-to-point communication between a pair of source and destination nodes, and cooperative relay broadcasting for broadcast services in this book. The performance of node cooperation frameworks is evaluated via mathematical analysis and computer simulations, in comparison with distributed TDMA MAC protocols without cooperation. The proposed node cooperation frameworks enhance the performance of distributed TDMA MAC and make it more robust to tackle the dynamic networking conditions in VANETs. Furthermore, with cooperation enabled transmission, the performance of distributed TMDA MAC is more suitable to support the wide range of mobile applications and their strict service requirements which is discussed in this book. The proposed node cooperation schemes and distributed cooperation decisions can be extended to wireless systems other than distributed TDMA MAC, such as cellular communication, for vehicular communications introduced in this book. This book is useful for researchers from academia and industry, as well as advanced level students interested in vehicular communication networks. It is also useful for professionals and engineers developing applications that use cooperative wireless communication systems.

Uncertainty regarding loading and system parameters leads to challenging optimization and robustness issues. Stochastic modeling combined with optimization theory ensures the optimum end-to-end performance of telecommunication or computer network systems. In view of the diverse design options possible, supporting models have many adjustable parameters and choosing the best set for a particular performance objective is delicate and time-consuming. An optimization based approach determines the optimal possible allocation for these parameters.

Researchers and graduate students working at the interface of telecommunications and operations research will benefit from this book. Due to the practical approach, this book will also serve as a reference tool for scientists and engineers in telecommunication and computer networks who depend upon optimization.

Intelligent/smart systems have become common practice in many engineering applications. On the other hand, current low cost standard CMOS technology (and future foreseeable developments) makes available enormous potentialities. The next breakthrough will be the design and development of "smart adaptive systems on silicon" i.e. very power and highly size efficient complete systems (i.e. sensing, computing and "actuating" actions) with intelligence on board on a single silicon die. Smart adaptive systems on silicon will be able to "adapt" autonomously to the changing environment and will be able to implement "intelligent" behaviour and both perceptual and cognitive tasks. At last, they will communicate through wireless channels, they will be battery supplied or remote powered (via inductive coupling) and they will be ubiquitous in our every day life.

Although many books deal with research and engineering topics (i.e. algorithms, technology, implementations, etc.) few of them try to bridge the gap between them and to address the issues related to feasibility, reliability and applications. Smart Adaptive Systems on Silicon, though not exhaustive, tries to fill this gap and to give answers mainly to the feasibility and reliability issues.

Smart Adaptive Systems on Silicon mainly focuses on the analog and mixed mode implementation on silicon because this approach is amenable of achieving impressive energy and size efficiency. Moreover, analog systems can be more easily interfaced with sensing and actuating devices.

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.

This book summarizes the proceedings of the invited talks presented at the International Symposium of Physics and Application of Optical Solitons in Fibers held in Kyoto during November 14 to 17,1995. As a result of worldwide demand for ultra high bitrate transmissions and increased scientific interests from the soliton community, research on optical solitons in fibers has made a remarkable progress in recent years. In view of these trends, and with the support of the Japanese Ministry of Posts and Telecommunications, the Research Group for Optical Soliton Communications (ROSC), chaired by Akira Hasegawa, was established in Japan in April 1995 to promote collaboration and information exchange 'among communication service companies, industries and academic circles in the theory and application of optical solitons. This symposium was organized as a part of the ROSC activities. The symposium attracted enthusiastic response by worldwide researchers involved in this subject which has lead to the most intensive meeting that the editor ever attended. The reader will find the contents to be well-balanced among theory, experiment and technology. Although the evaluation of the contents shall naturally depend on the particular area of interest of the reader, the symposium has confirmed that the soliton based light wave transmission has achieved the best result in one channel, both in distance of transmission and in bitrate although in wavelength division multiplexed (WDM) systems, NRZ transmission has yet better result.
