Book Description
Although the existing layering infrastructure--used globally for designing computers, data networks, and intelligent distributed systems and which connects various local and global communication services--is conceptually correct and pedagogically elegant, it is now well over 30 years old has started create a serious bottleneck. Using Cross-Layer Techniques for Communication Systems: Techniques and Applications explores how cross-layer methods provide ways to escape from the current communications model and overcome the challenges imposed by restrictive boundaries between layers. Written exclusively by well-established researchers, experts, and professional engineers, the book will present basic concepts, address different approaches for solving the cross-layer problem, investigate recent developments in cross-layer problems and solutions, and present the latest applications of the cross-layer in a variety of systems and networks.

Book Description
The book is devoted to advanced radiocommunication, discussing the merits and operational aspects of spread spectrum signalling. Spread spectrum modulation is emerging as one of the most important tools for combatting a wide range of problems usually encountered in radiocommunication. For military applications the signalling is able to resist difficulties deliberately introduced by an enemy, such as jamming and eavesdropping. For civil application, the efficient signal multiplexing and multipath rejection capability is of great interest. The price paid however is the need for very complex processing of the radio signals. This task put great challenges on new technologies and design, and it is only recently that operational systems have started to emerge from the laboratories. The book starts by comparing spread spectrum modulation and conventional modulation methods, and then discusses demodulation, which requires both special acquisition and synchronisation techniques. The electronic warfare scenario is introduced, discussing the principles of various spreading techniques and possible countermeasures. The coding for bandwidth spreading in a direct sequence spread spectrum system is treated by discussing the most common codes and their different figures of merit with respect to multipath, code division multiplexing and signal concealment. The book also illustrates the possible benefits, as well as limits to the use of new hardware technology to accomplish the various functions necessary for successful operation of a spread spectrum system. The effect of the propagation environment on spread spectrum is treated both analytically and through reported experiments and simulations. Finally the book considers the task of designing a complete communication network and discusses the usefulness and technology for additional interference suppressing techniques suitable to work with spread spectrum systems.

Book Description
This book provides a concise but lucid explanation of the fundamentals of spread-spectrum systems with an emphasis on theoretical principles. Throughout the book, learning is facilitated by many new or streamlined derivations of the classical theory. Problems at the end of each chapter are intended to assist readers in consolidating their knowledge and to provide practice in analytical techniques. The choice of specific topics is tempered by the author’s judgment of their practical significance and interest to both researchers and system designers. The evolution of spread spectrum communication systems and the prominence of new mathematical methods in their design provided the motivation to undertake this new edition of the book. This edition is intended to enable readers to understand the current state-of-the-art in this field. More than 20 percent of the material in this edition is new, including a chapter on systems with iterative channel estimation, and the remainder of the material has been thoroughly revised.

Book Description
ULTRA WIDEBAND WIRELESS COMMUNICATION AN INTERNATIONAL PANEL OF EXPERTS PROVIDE MAJOR RESEARCH ISSUES AND A SELF-CONTAINED, RAPID INTRODUCTION TO THE THEORY AND APPLICATION OF UWB This book delivers end-to-end coverage of recent advances in both the theory and practical design of ultra wideband (UWB) communication networks. Contributions offer a worldwide perspective on new and emerging applications, including WPAN, sensor and ad hoc networks, wireless telemetry, and telemedicine. The book explores issues related to the physical layer, medium access layer, and networking layer. Following an introductory chapter, the book explores three core areas: Analysis of physical layer and technology issues System design elements, including channel modeling, coexistence, and interference mitigation and control Review of MAC and network layer issues, up to the application Case studies present examples such as network and transceiver design, assisting the reader in understanding the application of theory to real-world tasks. Ultra Wideband Wireless Communication enables technical professionals, graduate students, engineers, scientists, and academic and professional researchers in mobile and wireless communications to become conversant with the latest theory and applications by offering a survey of all important topics in the field. It also serves as an advanced mathematical treatise; however, the book is organized to allow non-technical readers to bypass the mathematical treatments and still gain an excellent understanding of both theory and practice.
