Download or read book Digital Communication over Fading Channels written by Marvin K. Simon and published by John Wiley & Sons. This book was released on 2005-02-11 with total page 936 pages. Available in PDF, EPUB and Kindle. Book excerpt: The four short years since Digital Communication over Fading Channels became an instant classic have seen a virtual explosion of significant new work on the subject, both by the authors and by numerous researchers around the world. Foremost among these is a great deal of progress in the area of transmit diversity and space-time coding and the associated multiple input-multiple output (MIMO) channel. This new edition gathers these and other results, previously scattered throughout numerous publications, into a single convenient and informative volume. Like its predecessor, this Second Edition discusses in detail coherent and noncoherent communication systems as well as a large variety of fading channel models typical of communication links found in the real world. Coverage includes single- and multichannel reception and, in the case of the latter, a large variety of diversity types. The moment generating function (MGF)-based approach for performance analysis, introduced by the authors in the first edition and referred to in literally hundreds of publications, still represents the backbone of the book's presentation. Important features of this new edition include: * An all-new, comprehensive chapter on transmit diversity, space-time coding, and the MIMO channel, focusing on performance evaluation * Coverage of new and improved diversity schemes * Performance analyses of previously known schemes in new and different fading scenarios * A new chapter on the outage probability of cellular mobile radio systems * A new chapter on the capacity of fading channels * And much more Digital Communication over Fading Channels, Second Edition is an indispensable resource for graduate students, researchers investigating these systems, and practicing engineers responsible for evaluating their performance.

Download or read book Optical Channels written by Sherman Karp and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: When we were first approached by Dr. Lucky to write this book we were very enthusiastic about the prospect, since we had contemplated a similar project for quite some time. The difficulty lay in how best to digest the vast amount of data on optical propagation, reduce it to a book of manageable size, and simultaneously form the transition from the physics of propagation to the engineering of optical channels. This is the intent of Optical Channels. In accomplishing our goal it was necessary to condense the material on optical propagation and, in so doing, we have left a large amount to be handled via references. We have tried to make these decisions in a consistent manner so that the book will be uniform in its treatment of this topic. We identify four channels for consideration: the free-space channel, which: is characteristic of a tranquil atmosphere or a space-to-space link; the turbulent channel, which is characteristic of the atmospheric channel; the scatter channel in two forms, clouds and water; and the fiber optic channel. For each of these channels we have tried to reduce the applicable propagation theory to a level that can be used for engineering design. This has been done by example, but here again decisions had to be made on which examples to present. We have not tried to present any material on optical components and consequently other references on engineering would be necessary to supplement this book.

Download or read book Strategic Employee Communication written by Gail S. Thornton and published by Springer. This book was released on 2018-10-06 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Employee engagement (or a lack thereof) can often be linked to poor communication and a detachment from company goals. Companies of all sizes are looking for ways to boost communication, recognizing its impact on key business outcomes, such as productivity and profitability. This book offers fresh insights about opportunities to improve the quality of employee communications based on employees’ needs. It highlights the importance of simple, jargon-free communication that focuses on dialogue and content. High-performing organizations are more likely to think about communication from the audience perspective, rather than purely from the management perspective. The case studies offer readers a firm understanding of ways to implement and measure communication in daily practice. Effective communication requires planning and this book, with its focus on the US, Latin America, and emerging markets, will guide readers in using communication in the alignment of corporate and employee needs.

Download or read book Sacred Channels written by Erich Hörl and published by Amsterdam University Press. This book was released on 2019-01-16 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Erich Hörl's Sacred Channels is an original take on the history of communication theory and the cultural imaginary of communication understood through the notions of the sacred and the primitive. Hörl offers insight into the shared ground of anthropology and media theory in the nineteenth and twentieth centuries and presents an archeology of the philosophy of technology that underpins contemporary culture. This singular and unique project focuses on the ethnological disciplines and their phantasmatic imaginations of a prealphabetical realm of the sacred and the primitive but reads them in the context of media cultural questions as epistemic unconscious and as projections of the emerging postalphabetical condition. Drawing inspiration from work by the likes of Friedrich Kittler, Hörl's understanding of cybernetics in the post-World War II interdisciplinary field informs a rich analysis that is of interest to media scholars and to anyone seeking to understand the historical and theoretical underpinnings of the humanities in the age of technical media.
