Synchronization is a critical function in digital communications; its failures may have catastrophic effects on the transmission system performance. Furthermore, synchronization circuits comprehend such a large part of the receiver hardware that their implementation has a substantial impact on the overall costs. For these reasons design engineers are particularly concerned with the development of new and more efficient synchronization structures. Unfortunately, the advent of digital VLSI technology has radically affected modem design rules, to a point that most analog techniques employed so far have become totally obsolete. Although digital synchronization methods are well established by now in the literature, they only appear in the form of technical papers, often concentrating on specific performance or implementation issues. As a consequence they are hardly useful to give a unified view of an otherwise seemingly heterogeneous field. 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 task of the present book is just to develop such a framework.

Here's the first complete reference available on all of the modern reflector antenna analysis and design techniques. This book demystifies modern reflector antenna analysis by proceeding from the early numerical integration approaches to today's powerful techniques, such as the Jacobi-Bessel and Fourier-Bessel Methods.

Error Coding for Engineers provides a useful tool for practicing engineers, students, and researchers, focusing on the applied rather than the theoretical. It describes the processes involved in coding messages in such a way that, if errors occur during transmission or storage, they are detected and, if necessary, corrected. Very little knowledge beyond a basic understanding of binary manipulation and Boolean algebra is assumed, making the subject accessible to a broad readership including non-specialists. The approach is tutorial: numerous examples, illustrations, and tables are included, along with over 30 pages of hands-on exercises and solutions. Error coding is essential in many modern engineering applications. Engineers involved in communications design, DSP-based applications, IC design, protocol design, storage solutions, and memory product design are among those who will find the book to be a valuable reference. Error Coding for Engineers is also suitable as a text for basic and advanced university courses in communications and engineering.

A color time-varying image can be described as a three-dimensional vector (representing the colors in an appropriate color space) defined on a three-dimensional spatiotemporal space. In conventional analog television a one-dimensional signal suitable for transmission over a communication channel is obtained by sampling the scene in the vertical and tem poral directions and by frequency-multiplexing the luminance and chrominance informa tion. In digital processing and transmission systems, sampling is applied in the horizontal direction, too, on a signal which has been already scanned in the vertical and temporal directions or directly in three dimensions when using some solid-state sensor. As a conse quence, in recent years it has been considered quite natural to assess the potential advan tages arising from an entire multidimensional approach to the processing of video signals. As a simple but significant example, a composite color video signal, such as the conven tional PAL or NTSC signal, possesses a three-dimensional spectrum which, by using suitable three-dimensional filters, permits horizontal sampling at a rate which is less than that re quired for correctly sampling the equivalent one-dimensional signal. More recently it has been widely recognized that the improvement of the picture quality in current and advanced television systems requires well-chosen signal processing algorithms which are multidimen sional in nature within the demanding constraints of a real-time implementation."

The ability to process signals at multiple sampling rates can help reduce costs and improve performance in many DSP applications ranging from signal compression to wireless communications, consumer entertainment products and sensor networks. The theory of multirate signal processing has witnessed a great deal of progress since the publication of the first textbook by Ronald E. Crochiere and Lawrence R. Rabiner in 1983. However, this progress has been mainly in the area of deterministic systems with emphasis on perfect-reconstruction filter banks, orthogonal filter banks, systems with the same sampling rate across all channels and tree-structured systems.

Communications using the high frequency spectrum (2--30 MHz) have experienced a considerable resurgence. In recent years, powerful microcomputers and VLSI technology have greatly enhanced the prospects of overcoming many of the unique problems that formerly afflicted the HF systems designer. The aim of this book, therefore, is to provide a firm foundation for the design, evaluation and operational use of HF communications, with systems issues as the primary perspective. The approach provides an understanding of the way in which various elements of the system contribute to the overall HF communications link performance. Mathematics is introduced only where needed to clarify or illustrate key issues. The book will be vital to the professional communications engineer, already familiar with many of the problems but requiring a consolidated systems view of the subject; to the engineering student and research worker as a reference text which demonstrates how modern technology can be used to solve problems posed to the HF user; and to non- specialists and consultants within the communications industry.

This volume, which grew out of a study conducted by the East-West Center, analyzes the friction in telecommunications trade between the United States and Japan and the consequent imposition of the Super 301 clause on Japan. Giving both the U.S. and Japanese viewpoints, the book discusses trade in telecommunications and the events that led to the Super 301 clause and the Strategic Impediments Initiative. It also provides an in-depth analysis of GATT issues and what may be expected from the current Uruguay Round. Telecommunications deregulation and privatization in both countries are carefully assessed as are the social, policial, and cultural implications of the trade conflict, which led to President Bush's recent visit to Japan. The first book to focus specifically on trade in communications equipment between the United States and Japan, the volume fills a critical gap in the literature.
