Synchronization is a critical function in digital communications; It is widely recognized that a fundamental understanding of digital synchronization can only be reached by providing the designer with a solid theoretical framework, or else he will not know where to adjust his methods when he attempts to apply them to new situations.

The motivation for this book stems from an early exposure to the book Ap plied Mechanics by John Perry. The reader should not need to be able to derive formulas in order to apply them just as, to quote Professor Perry, "He should not have to be able to design a watch in order to tell time ...

In response to the increasing interest in developing photonic switching fabrics, this book gives an overview of the many technologies from a systems designer's perspective. Optically transparent devices, optical logic devices, and optical hardware are all discussed in detail and set into a systems context.

In deep space, communications propagation is good, relative to terrestrial communications, and there is an opportunity to press toward the mathematical limit of microwave communication. Communication capability measured in 18 bits per second at a given range rose by a factor of 10 in the 19 years from Explorer I of 1958 to Voyager of 1977.

Since the publication of the first edition of Fundamentals of Digital Switching in 1983, there has been substantial improvement in digital switching technology and in digital networks.

Computer communications is one of the most rapidly developing technologies and it is a subject with which everyone in the computer systems profession should be familiar. Computer communications and networks is an introduction to communications technology and system design for practising and aspiring computer professionals.

This is a book about the bricks and mortar from which are built those edifices that will permeate the emerging information society of the future-computer networks. The study of how computer networks function is a combined study of communication theory and computer science, two disciplines appearing to have very little in common.

In this book, I am seeking to provide a much broader perspective which includes information on the motives driving the business itself, on new media and services, and on advancing technologies, as well as on digital facilities and their integration into the environment of future businesses and households.

The characteristics of this data traffic and the associated perfor mance requirements are quite different from those of voice traffic. The subject of this book is the mathematical modeling and analysis of computer communications networks, that is to say, the multiplexing and switching techniques that have been developed for data traffic.

This unique text, for both the first year graduate student and the newcomer to the field, provides in-depth coverage of the basic principles of data communications and covers material which is not treated in other texts, including phase and timing recovery and echo cancellation.

Basic Concepts in Information Theory and Coding is an outgrowth of a one semester introductory course that has been taught at the University of Southern California since the mid-1960s.

The last ten years have seen a great flowering of the theory of digital data modulation. Now the older disciplines of detection theory and coding theory have been generalized and applied to the point where it is hard to tell where these end and the theories of signal design and modulation begin.

Focuses on the fundamentals of operation, architectures, performance management, and protocols of integrated broadband networks capable of supporting voice, data, image, and video telecommunication transport and services. This book offers an introduction to the field for systems designers, hardware and software engineers, and R&D managers.

This book is an outgrowth of a course given by the author for people in industry, government, and universities wishing to understand the implica tions of emerging optical fiber technology, and how this technology can be applied to their specific information transport and sensing system needs.

The Second Edition details the established international standards for digital imagery. Chapters discuss standards for the digitalization of bilevel images, color pictures, video conferencing, and television.

Error-correction coding is being used on an almost routine basis in most new communication systems. Not only is coding equipment being used to increase the energy efficiency of communication links, but coding ideas are also providing innovative solutions to many related communication problems.

With the evolution of digital techniques for information processing, storage, and transmission, the need arises for digital representation of visual information, that is, the representation of images by a sequence of integer numbers (usually binary).

Such computer networks are playing an increasing role in our daily lives, somewhat indirectly up to now as the hidden servants of banks, retail credit bureaus, airline reservation offices, and so forth, but soon they will become more visible as they enter our offices and homes and directly become part of our work, entertainment, and daily living.
