Book Description
As a result of higher frequencies and increased user mobility, researchers and systems designers are shifting their focus from time-invariant models to channels that vary within a block. Wireless Communications Over Rapidly Time-Varying Channels explains the latest theoretical advances and practical methods to give an understanding of rapidly time varying channels, together with performance trade-offs and potential performance gains, providing the expertise to develop future wireless systems technology. As well as an overview of the issues of developing wireless systems using time-varying channels, the book gives extensive coverage to methods for estimating and equalizing rapidly time-varying channels, including a discussion of training data optimization, as well as providing models and transceiver methods for time-varying ultra-wideband channels. An introduction to time-varying channel models gives in a nutshell the important issues of developing wireless systems technology using time-varying channels Extensive coverage of methods for estimating and equalizing rapidly time-varying channels, including a discussion of training data optimization, enables development of high performance wireless systems Chapters on transceiver design for OFDM and receiver algorithms for MIMO communication channels over time-varying channels, with an emphasis on modern iterative turbo-style architectures, demonstrates how these important technologies can optimize future wireless systems

Book Description
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.

Book Description
This report summarizes presentations and discussions at the Workshop on the Social Processes Underlying Fertility Change in Developing Countries, organized by the Committee on Population of the National Research Council (NRC) in Washington, D.C., January 29-30, 1998. Fourteen papers were presented at the workshop; they represented both theoretical and empirical perspectives and shed new light on the role that diffusion processes may play in fertility transition. These papers served as the basis for the discussion that is summarized in this report.

Book Description
Narration can be conceptualized as conveying two or more events (or an event with a situation) that are logically interrelated and take place over time and have a consistent topic. The concept includes every storytelling text. The advertisement is one of the text types that includes a story, and the phenomenon conceptualized as advertising narration has gained new dimensions with the widespread use of digital media. The Handbook of Research on Narrative Advertising is an essential reference source that investigates fundamental marketing concepts and addresses the new dimensions of advertising with the universal use of digital media. Featuring research on topics such as branding, mobile marketing, and consumer engagement, business professionals, copywriters, students, and practitioners will find this text useful in furthering their research exposure to evolutionary techniques in advertising.

Book Description
Wireless Communications over MIMO Channels: Applications to CDMA and Multiple Antenna Systems covers both, state-of-the-art channel coding concepts and CDMA and multiple antenna systems, rarely found in other books on the subject. Furthermore, an information theoretical analysis of CDMA and SDMA systems illuminate ultimate limits and demonstrates the high potential of these concepts. Besides spatial multiplexing, the use of multiple transmit antennas in order to increase the link reliability by diversity concepts (space-time coding) is described. Another focus is the application of error control coding in mobile radio communications Accompanying appendices include: basic derivations, tables of frequently used channel models, chain rules for entropy and information, data processing theorem, basics of linear algebra, Householder reflection and Givens rotation, and the LLL algorithm for lattice reduction.

Book Description
What sources of information do tourists consult when choosing a travel destination? How can communication channels be used to reach the tourist market for a specific region? This resource provides new insight into these important questions and more on developing tourism marketing strategies using the key factors of communication and channel systems. Communication and Channel Systems in Tourism Marketing features both conceptual and applied research which provides an excellent base for tourism marketers and destination planners to evaluate and improve their overall tourism marketing programs. Tourism and hospitality scholars discuss communication distribution channels, media selection, information needs and sources, importance of travel brochures and slogans, brochure design, and the effectiveness of communication messages in tourism marketing. The advantages and disadvantages of a wide variety of communication channels are explored including word-of-mouth, brochures/pamphlets, travel agents, magazines, radio, television, and slogans. Some of the topics covered in this book that demonstrate the use of communication and channel systems in tourism marketing are: building repeat visitor relationships image formation distribution channels communication messages and their effectiveness design of destination- and attraction-specific brochures communicating unique selling propositions in slogans This groundbreaking book presents original, empirical research that incorporates communications and channels systems as integral components of tourism marketing. The diversity and originality of these tourism research cases will be helpful to destination promoters, tourism decisionmakers, and tourism planners worldwide. Communication and Channel Systems in Tourism Marketing is also a valuable supplementary text for students in courses on leisure, recreation, hospitality, tourism, and marketing.
