This is a concise introduction into optical fiber communication. It covers important aspects from the physics of optical wave propagation and amplification to the essentials of modulation formats and receivers. The combination of a solid coverage of necessary fundamental theory with an in-depth discussion of recent relevant research results enables the reader to design modern optical fiber communication systems. The book serves both graduate students and professionals. It includes many worked examples with solutions for lecturers. For the second edition, Reinhold Noe made many changes and additions throughout the text so that this concise book presents the essentials of optical fiber communication in an easy readable and understandable way.

Ethics in Technical Communication provides students and practitioners with a clear introduction to ethics--from Aristotle through the present--and suggests how these accounts can help technical communicators think through the kinds of dilemmas that inevitably arise in their working lives. Markel critiques current scholarship linking ethics and technical communication, then presents a flexible model for ethical decision-making that draws on the values of rights, justice, utility, and care. He then applies the model in examining the technical communicator's obligations in five critical areas: truthtelling, liability, multicultural communication, intellectual property, and codes of conduct. Markel first defines key terms, justifies the examination of ethics and technical communication, surveys the scholarly literature on the subject, and describes some of the basic assumptions underlying a serious study of ethics. Next, he presents concise overviews of Kantian rights and utilitarianism, the transitional ethical theories of the early 20th century, and several strands of contemporary ethical theory, including virtue ethics, the ethic of care, and postmodern ethics. He then explores his own approach, which calls for a fluid, non-hierarchical analysis conducted in an open-, non-coercive environment, as described in contemporary accounts of discourse ethics. This approach is used in the second part of the book, which focuses on truthtelling, liability, multiculturalism, intellectual property, and codes of conduct. In each of these chapters, Markel defines the problem, summarizes and critiques the scholarly literature, presents an approach to thinking about the problem sensitively andrealistically, and concludes with a case and a response to it.

Pipelined Lattice and Wave Digital Recursive Filters uses look-ahead transformation and constrained filter design approaches. It is also shown that pipelining often reduces the roundoff noise in a digital filter. The pipelined recursive lattice and wave digital filters presented are well suited where increasing speed and reducing area or power or roundoff noise are important. Examples are wireless and cellular codec applications, where low power consumption is important, and radar and video applications, where higher speed is important. The book presents pipelining of direct-form recursive digital filters and demonstrates the usefulness of these topologies in high-speed and low-power applications. It then discusses fundamentals of scaling in the design of lattice and wave digital filters. Approaches to designing four different types of lattice digital filters are discussed, including basic, one-multiplier, normalized, and scaled normalized structures. The roundoff noise in these lattice filters is also studied. The book then presents approaches to the design of pipelined lattice digital filters for the same four types of structures, followed by pipelining of orthogonal double-rotation digital filters, which eliminate limit cycle problems. A discussion of pipelining of lattice wave digital filters follows, showing how linear phase, narrow-band, sharp-transition recursive filters can be implemented using this structure. This example is motivated by a difficult filter design problem in a wireless codec application. Finally, pipelining of ladder wave digital filters is discussed. Pipelined Lattice and Wave Digital Recursive Filters serves as an excellent reference and may be used as a text for advanced courses on the subject.

The GSM system is undoubtedly the most successful second-generation digital mobile radio system. One of the key factors for this exceptional performance is the constant evolution of the GSM system and its derivatives. GSM: Evolution towards 3rd generation systems addresses new concepts in the GSM system, dealing both with standardized features as well as with theoretically and technologically feasible improvements which contribute to evolutionary changes in general. Ongoing efforts in GSM standardization are focused on Phase 2+ with gradual additions for a fast and modular evolution. Speech remains the prime service of cellular systems, with ongoing work on spectral efficiency taking into account the tradeoff between cost of the system and transmission quality. Most of the notable results from novel speech service implementations are addressed herein such as new EFR speech codec and Advanced Speech Cell Items (ASCI). Data capability in Phase 2+ has been covered under General Packet Radio Service (GPRS) and High-Speed Circuit Switched Data (HCSD) work items. Initiatives under CAMEL cover intelligent networking (IN) within the GSM framework. Dual mode operation in GSM includes not only dual-band solutions but also inter-networking with other systems like DECT or satellite systems. Numerous specific wireless applications such as inbuilding communications, WLL, etc., have also been developed based on GSM. To support the required changes a number of issues have to be solved in the radio part of the system. Deployment of adaptive antenna arrays for enhanced quality, interference suppression techniques and slow frequency hopping are among the techniques presented in the GSM framework. Dynamicevolution of GSM presents a platform for the introduction of UMTS. Presently, efforts are directed towards the standardization of the UMTS air interface in ETSI. Major trends in progress towards new radio interfaces are outlined including contributions from pan-European projects such as ATDMA, which was carried out under the RACE II framework, and the ACTS project AC090 FRAMES. GSM: Evolution towards 3rd generation systems comprises a collection of specially written contributions from GSM specialists. The information presented is essential reading for all researchers, engineers and managers working on GSM and third generation wireless systems. This book covers the most important advances in GSM that will have lasting impact on the system influencing third generation wireless systems.

This is an elementary textbook on an advanced topic: broadband telecommunica tion networks. I must declare at the outset that this book is not primarily intended for an audience of telecommunication specialists who are weIl versed in the concepts, system architectures, and underlying technologies of high-speed, multi media, bandwidth-on-demand, packet-switching networks, although the techni caIly sophisticated telecommunication practitioner may wish to use it as a refer ence. Nor is this book intended to be an advanced textbook on the subject of broadband networks. Rather, this book is primarily intended for those eager to leam more about this exciting fron tier in the field of telecommunications, an audience that includes systems designers, hardware and software engineers, en gineering students, R&D managers, and market planners who seek an understand ing of local-, metropolitan-, and wide-area broadband networks for integrating voice, data, image, and video. Its primary audience also includes researchers and engineers from other disciplines or other branches of telecommunications who anticipate a future involvement in, or who would simply like to leam more about, the field of broadband networks, along with scientific researchers and corporate telecommunication and data communication managers whose increasingly sophis ticated applications would benefit from (and drive the need for) broadband net works. Advanced topics are certainly not ignored (in fact, a plausible argument could be mounted that aIl of the material is advanced, given the infancy of the topic)."

Multirate Switched-Capacitor Circuits for 2-D Signal Processing introduces the concepts of analog multirate signal processing for the efficient implementation of two-dimensional (2-D) filtering in integrated circuit form, particularly from the viewpoints of silicon area and power dissipation. New 2-D switched-capacitor (SC) networks and design techniques are presented, both with finite impulse response (FIR) and infinite impulse response (IIR) with separable denominator polynomial, which offer simpler and more systematic synthesis procedures than currently available design techniques for 2-D analog filters. Since they are in the discrete-time domain, the book can be also referred to the digital multirate signal processing. A 2-D SC image processor that realizes both (2 x 2)nd-order Butterworth lowpass and highpass filtering functions for video image signals was realized as a prototype integrated circuit implemented in 1.0-mum CMOS technology. The experimental characterization of this prototype chip demonstrated the feasibility of real-time analog multirate 2-D image processing with equivalent 8-bits accuracy, using only 2.5 x 3.0 mm2 of silicon area and dissipating as little as 85 mW at 5V supply and 18 MHz sampling rate. This indicates that for moderate accuracy and low to moderate complexity of the filtering function, a fully multirate analog implementation has a potential to achieve a more competitive implementation than an alternative digital VLSI implementation. However, for high accuracy and/or higher processing complexity, not only the relative overhead cost of the front-end and back-end converters will diminish but also the implementation of the processing core in digital VLSI will benefit more of technology scaling to achieve higher density of integration. Multirate Switched-Capacitor Circuits for 2-D Signal Processing is essential reading for practicing analog design engineers and researchers in the field. It is also suitable as a text for an advanced course on the subject.

Chaos and nonlinear dynamics initially developed as a new emergent field with its foundation in physics and applied mathematics. The highly generic, interdisciplinary quality of the insights gained in the last few decades has spawned myriad applications in almost all branches of science and technology-and even well beyond. Wherever the quantitative modeling and analysis of complex, nonlinear phenomena are required, chaos theory and its methods can play a key role.
This second volume concentrates on reviewing further relevant, contemporary applications of chaotic nonlinear systems as they apply to the various cutting-edge branches of engineering. This encompasses, but is not limited to, topics such as the spread of epidemics; electronic circuits; chaos control in mechanical devices; secure communication; and digital watermarking.
Featuring contributions from active and leading research groups, this collection is ideal both as a reference work and as a 'recipe book' full of tried and tested, successful engineering applications."

This reader-friendly resource covers the broad spectrum of satellite principles and their associated technologies. While other books limit their coverage to specialized services or to satellite payloads such as communication satellites, Satellite Systems focuses upon the methodology of launching satellites, keeping them there, the environments under which they operate, and other facets particular to their operation. Pattan's detailed, elaborate approach does not assume that the reader is versed in esoteric mathematics.

• ADSL-based access networks

• Signalling

• PNNI (Private Network Node Interface)

The rapid development of optical fiber transmission technology has created the possibility for constructing digital networks that are as ubiquitous as the current voice network but which can carry video, voice, and data in massive qlJantities. How and when such networks will evolve, who will pay for them, and what new applications will use them is anyone's guess. There appears to be no doubt, however, that the trend in telecommunication networks is toward far greater transmission speeds and toward greater heterogeneity in the requirements of different applications. This book treats some of the central problems involved in these networks of the future. First, how does one switch data at speeds orders of magnitude faster than that of existing networks? This problem has roots in both classical switching for telephony and in switching for packet networks. There are a number of new twists here, however. The first is that the high speeds necessitate the use of highly parallel processing and place a high premium on computational simplicity. The second is that the required data speeds and allowable delays of different applications differ by many orders of magnitude. The third is that it might be desirable to support both point to point applications and also applications involving broadcast from one source to a large set of destinations.

In this book signals or images described by functions whose number of arguments varies from one to five are considered. This arguments can be time, spatial dimensions, or wavelength in a polychromatic signal. The book discusses the basics of mathematical models of signals, their transformations in technical pre-processing systems, and criteria of the systems quality. The models are used for the solution of practical tasks of system analysis, measurement and optimization, and signal restoration. Several examples are given.

Planning and Architectural Design of Integrated Services Digital Networks: Civil and Military Applications provides a comprehensive treatment of ISDNs: how to plan and design them architecturally and how to implement them so that they meet certain given user requirements ranging from a variety of service demands to transmission performance, security, reliability/availability, capability for growth, interoperability with other ISDN and non-ISDN networks and, of course, cost. The book concentrates on the application of ISDN concepts and standards to the planning and design of real costed networks to meet certain specified user requirements. Where there are multiple options, considerations and rationale on the choice of network aspects and standards are discussed. The unique feature of the book, compared with other books on ISDN, is that it expounds an original methodology which starts from an assumed or given set of complete user requirements and proceeds to designing a complete network taking into account the technology and standards of ISDN, as well as some constraints including cost which may be imposed. Planning and Architectural Design of Integrated Services Digital Networks describes computer-aided design tools employed for dimensioning the network for various traffic loads and for assessing its traffic carrying performance for assessing different precedence categories and network configurations, transmission conditions and routing algorithms which may be static-deterministic or dynamic-adaptive. Aspects such as surveillance and control, security, survivability and EMP protection are also addressed. Planning and Architectural Design of Integrated Services Digital Networks: Civil and Military Applications is an excellent reference source and may be used as a text for advanced courses on the subject.

Finally, Moulin considers the problem of forming radar images under a diffuse-target statistical model. His estimation approach includes application of the maximum-likelihood principle and a regularization procedure based on wavelet representations. In addition, he shows that the radar imaging problem can be seen as a problem of inference on the wavelet coefficients of an image corrupted by additive noise. The aim of this special issue is to provide a forum in which researchers from the fields of mathematics, computer science, and electrical engineering who work on problems of significance to computer vision can better understand each other. I hope that the papers included in this special issue will provide a clearer picture of the role of wavelet transforms and the principles of multiresolution analysis. I wish to thank many people for their contributions and assistance in this project: Gerhard Ritter, the Editor-in-Chief of the Journal of Mathematical Imaging and Vision, who invited me to organize this issue and who provided patient guidance; the researchers who submitted papers for consideration and others who have contributed to the explosion of growth in this area; the reviewers, who provided careful and thoughtful evaluations in a timely fashion; and, finally, from these efforts, the authors of the papers selected for publication in the special issue.

With the proliferation of ISDN and mobile communication systems, modern commu nication networks are becoming larger-scale, higher-speed, and more complex than ever before. Therefore, besides hardware development, extensive research on system technolo gies with respect to the performance evaluation and management is indispensable for the proper design, development and operation of future complex communication networks. The International Conference on the Performance and Management of Complex Com munication Systems (PMCCN '97) was held from November 17 to 21, 1997, at Tsukuba Science City, Japan. This was the fifth international conference on the performance as pects of communication networks held every three years in Japan (1985 in Tokyo; 1988, 1991, and 1994 in Kyoto). The conference was sponsored by the International Federa tion of Information Processing (IFIP) Working Group (WG) 6.3 Performance of Com munication Systems, and 7.3 Computer System Modelling, University of Tsukuba, Kyoto University, and The Telecommunication Advancement Foundation (TAF)."

Hardbound. The convergence of telecommunications, mass media and computer technologies has brought spectacular developments of ubiquitous intelligent interconnected systems. In the course of these evolutionary changes, debate and policy has swung again towards privatization, deregulation and increased reliance upon competition. Nevertheless, the underlying and powerful role of new information continues to bring so much restructuring and organizational change, that a reassessment of ideas about competition in this dynamic context, is essential. The aim of this volume is to provide an update of research and policy debates in this important field. An international perspective is provided with contributions from academic, business and governmental communities. The volume will be invaluable to researchers in telecommunications and information activities; decision-makers in industry, government and regulatory fields; consultants; and information service provide
