Included is an analysis of the degradation of the performance of noncoherent binary FSK and carrier keyed systems due to a frequency offset of the received signal. The optimization of systems operating over dispersive channels in the presence of nonwhite, gaussian noise is treated and the effects of medium phase perturbations on the performance of digital systems are analyzed. Partial orderings of digital channels specified by their transition probabilities are also investigated. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Since the 1970's, there has been a great deal of research effort spent on studying chaotic systems and the properties of the chaotic signals generated. Characterized by their wideband, impulse-like autocorrelation and low cross-correlation properties, chaotic signals are useful spread-spectrum signals for carrying digital information. Spectrum spreading has become one of the most popular modulation techniques for high-speed wireless communications. It makes use of signals of very wide bandwidth to carry information at relatively low data rates, and possesses advantages such as low probability of interception, resistance to jamming, multiple-access capability and mitigation to multipath effect, which are particularly important in a wireless scenario. In addition to enjoying the aforementioned benefits, chaotic signals can be generated using simple circuitries, thus lowering the cost of transceivers. Early study of chaos-based communication systems was focused on a single-user case. In the past few years, more effort has been put on investigating systems with multiple-access capability, which is a key feature of spread-spectrum communication systems. Digital Communications with Chaos presents a detailed study of some multiple-access schemes used for chaos-based communications, and evaluates their performance. In addition, the effectiveness of the multiuser detection techniques, whose primary objective is to reduce interference between users and hence improve performance, is evaluated in the context of multiple-access digital communication systems. Hot research topic Describes communication technologies for the future Authors among the pioneers researching in chaos-based communications

Download or read book Digital Transmission Systems written by David R. Smith and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the development of telecommunication networks throughout the world, digital transmission has now replaced analog transmission as the predominant choice for new transmission facilities. This trend began in the early 1960s when the American Telephone and Telegraph Company first introduced pulse code modulation as a means of increasing capacity in their cable plant. Since that time, digital transmission applications have grown dramatically, notably in the United States, Canada, Japan, and Western Europe. With the rapidity of digital transmission developments and imple mentation, however, there has been a surprising lack of textbooks written on the subject. This book grew out of my work, research, and teaching in digital transmission systems. My objective is to provide an overview of the subject. To accomplish this end, theory has been blended with practice in order to illustrate how one applies theoretical principles to actual design and imple mentation. The book has abundant design examples and references to actual systems. These examples have been drawn from common carriers, manufac turers, and my own experience. Considerable effort has been made to include up-to-date standards, such as those published by the CCITT and CCIR, and to interpret their recommendations in the context of present-day digital transmission systems.

Available in PDF, EPUB and Kindle. Book excerpt: The results of fundamental investigations on a variety of topics related to the optimization of analog and digital data communication systems are presented. The maximum likelihood estimation of FM-modulated signals is investigated. A study is made of theshold phenomenon in FM reception with an ideal discriminator and a postdetection Wiener filter for the case of a random modulation function. Information theory is applied to establish bounds on the performance of analog communications systems. The performance of PCM systems for transmitting analog information is investigated and compared with theoretical bounds for systems of prescribed complexity. Previous work on the partial ordering of digital channels by the criterion of inclusion was extended. The analysis of the optimization of N-ary digital systems operating over a dispersive channel, which was begun during a previous phase of the contract, is further advanced.
