This book was released on 1982 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Frequency hopping has long been regarded as an effective technique to thwart intentional and unintentional interference. The latter includes also fading and multipath. An advantage of frequency hopping, as compared to direct sequence spread spectrum techniques, is that phase coherence is not required. This makes frequency hopped systems more robust, since they are dependent on one less parameter, which is particularly significant for fading channels wherein rapid phase variations make it difficult if not impossible to track. On the negative side, noncoherent systems performance is inferior to coherent systems, particularly when the number of bits per hop is small (or worse yet, fractional). More serious is the fact that tone or partial band jammers can cause severe degradations (of orders of magnitude) relative to full band Gaussian jammers.

Download or read book Introduction to Spread spectrum Communications written by Roger L. Peterson and published by Pearson. This book was released on 1995 with total page 718 pages. Available in PDF, EPUB and Kindle. Book excerpt: Besides the traditional military application areas, there is a growing and intense interest in spread spectrum communications systems for evolving civil applications, e.g., cellular-mobile communications, personal communications, and satellite-mobile communications. Ideal for those who need to get up to speed or current quickly in this area, this self-contained exploration of spread spectrum system analysis and applications provides a solid theoretical background along with an abundance of examples of specific analysis/design situations, and exposes readers to the most recent research and developments in the field. Covers basic digital communication and spread spectrum concepts, and features exceptionally complete treatments of important hot topics such as spectrum spreading sequences; the code acquisition and tracking process; the effects of jamming on spread spectrum communications and the use of coding/interleaving to combat the detrimental effects of jamming; designing spread spectrum systems for low probability of the intercept; and the design of code division multiple access systems, wit h examples. Contains a complete set of technical appendices. For electrical engineers and others with a background in linear systems and probability/random processes who want a cutting-edge overview of the principles, research, and developments of spread spectrum systems.

This book was released on 2018-11-01 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, rate-splitting based interference exploitation has been investigated in order to bridge theory and practice. The results shows that conventional detection-decoding techniques cannot provide desirable results within a reasonable complexity and thereby substantially reduce interference mitigation gains. A multi-layer rate splitting scheme is proposed to deal with this obstacle. This multi-layer rate splitting scheme can approach or achieve the same maximum sum rate as that achieved by joint decoding.

This book was released on 2011-07-15 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
