I remember vividly the ?rst time that I heard about the ?ber ampli?er. At that time, of course, it was the erbium-doped ?ber ampli?er, the predecessor of the Raman ampli?er that is the subject of this book. It was an early morning in a forgotten year in Murray Hill, New Jersey at one of our Bell Labs monthly research staff meetings. About twenty directors and executive directors of research organizations clustered around a long table in the imposing executive conference room. Arno Penzias, the vice president of research, presided at the foot of the table. Everyone who participated in those research staff meetings will long remember their culture and atmosphere. Arno would pick an arbitrary starting point somewhere around the table, and the designated person would head to the front of the table to give a short talk on “something new” in his or her research area. This ?rst speaker would invariably ?ddle helplessly with the controls embedded in the podium that controlled the viewgraph projector, but eventually we would hear machinery grinding in the back room as a large hidden mirror moved into place. We would all wait quietly, arranging and choosing our own viewgraphs from the piles that lay on the table in front of every participant.

Digital Television deals with all present-day TV transmission methods, i.e. MPEG, DVB, ATSC and ISDB-T. The DVD Video is also discussed to some extent. The discussion is focussed on dealing with these subjects in as practical a way as possible. Although mathematical formulations are used, they are in most cases only utilized to supplement the text. The book also contains chapters dealing with basic concepts such as digital modulation or transformations into the frequency domain. A major emphasis is placed on the measuring techniques used on these various digital TV signals. Practical examples and hints concerning measurement are provided. The book starts with the analog TV baseband signal and then continues with the MPEG-2 data stream, digital video, digital audio and the compression methods. After an excursion into the digital modulation methods, all the mentioned transmission methods are discussed in detail. Interspersed between these are found the chapters on the relevant measuring technique.

This book is an introduction to the mathematical description of information in science and engineering. The necessary mathematical theory will be treated in a more vivid way than in the usual theorem-proof structure. This enables the reader to develop an idea of the connections between different information measures and to understand the trains of thoughts in their derivation. As there exist a great number of different possible ways to describe information, these measures are presented in a coherent manner. Some examples of the information measures examined are: Shannon information, applied in coding theory; Akaike information criterion, used in system identification to determine auto-regressive models and in neural networks to identify the number of neu-rons; and Cramer-Rao bound or Fisher information, describing the minimal variances achieved by unbiased estimators. This softcover edition addresses researchers and students in electrical engineering, particularly in control and communications, physics, and applied mathematics.

Frequency Assignment and Network Planning for Digital Terrestrial Broadcasting Systems focuses on Digital Audio Broadcasting and Digital Video Broadcasting. The author provides a concise introduction to the subject and presents principles, concepts and commonly accepted methods used in the planning process. The frequency assignment material focuses on allotment planning while network planning is dealt with mainly from a network optimization perspective. All methods introduced and mathematical tools presented are fully explained. General concepts are illustrated with the help of several planning scenarios both for frequency assignment and network planning. Frequency assignment and network planning are vital issues throughout most of Europe and North America as a direct consequence of the increasing demand for digital communication systems.

WithgreatpleasurewewelcomedtheattendeestoEWSN2004,the1stEuropean Workshop on Wireless Sensor Networks, held in the exciting and lively city of Berlin. Wireless sensor networks are a key technology for new ways of interaction betweencomputersandthephysicalenvironmentwhichsurroundsus.Compared to traditional networking technologies, wireless sensor networks are faced with a rather unique mix of challenges: scalability, energy e?ciency, self-con?guration, constrainedcomputationandmemoryresourcesinindividualnodes,data-cent- city, and interaction with the physical environment, to name but a few. The goal of this workshop is to create a forum for presenting new results in the ?ourishing ?eld of wireless sensor networks. By bringing together academia and industry we hope to stimulate new opportunities for collaborations. In compiling the scienti?c program we have been quite selective. Thanks to the e?orts of 90 reviewers who delivered 252 reviews for the 76 papers originally submitted from all over the world, a strong selection of the 24 best contributions was made possible. The Technical Program Committee created an outstanding program covering the broad scope of this highly interdisciplinary ?eld: from distributed signal processing through networking and middleware issues to - plication experience. Running such a workshop requires dedication and much work from many people. We want to thank in particular Petra Hutt, Irene Ostertag and Heike Klemz for their valuable and esteemed help in the local organization of this workshop. We hope that you enjoy this volume, and if you were lucky enough to - tend we hope that you enjoyed the discussions with colleagues working in this fascinating area.
