Wireless technology is a truly revolutionary paradigm shift, enabling multimedia communications between people and devices from any location. It also underpins exciting applications such as sensor ...networks, smart homes, telemedicine, and automated highways. This book, first published in 2005, provides a comprehensive introduction to the underlying theory, design techniques and analytical tools of wireless communications, focusing primarily on the core principles of wireless system design. The book begins with an overview of wireless systems and standards. The characteristics of the wireless channel are then described, including their fundamental capacity limits. Various modulation, coding, and signal processing schemes are then discussed in detail, including state-of-the-art adaptive modulation, multicarrier, spread spectrum, and multiple antenna techniques. The concluding chapters deal with multiuser communications, cellular system design, and ad-hoc network design. Design insights and tradeoffs are emphasized throughout the book. It contains many worked examples, over 200 figures, almost 300 homework exercises, over 700 references, and is an ideal textbook for students.
Compressed sensing is an exciting, rapidly growing field, attracting considerable attention in electrical engineering, applied mathematics, statistics and computer science. This book provides the ...first detailed introduction to the subject, highlighting recent theoretical advances and a range of applications, as well as outlining numerous remaining research challenges. After a thorough review of the basic theory, many cutting-edge techniques are presented, including advanced signal modeling, sub-Nyquist sampling of analog signals, non-asymptotic analysis of random matrices, adaptive sensing, greedy algorithms and use of graphical models. All chapters are written by leading researchers in the field, and consistent style and notation are utilized throughout. Key background information and clear definitions make this an ideal resource for researchers, graduate students and practitioners wanting to join this exciting research area. It can also serve as a supplementary textbook for courses on computer vision, coding theory, signal processing, image processing and algorithms for efficient data processing.
A provocative analysis of net neutrality and a call to democratize online communication This short book is both a primer that explains the history and politics of net neutrality and an argument for a ...more equitable framework for regulating access to the internet. Pickard and Berman argue that we should not see internet service as a commodity but as a public good necessary for sustaining democratic society in the twenty-first century. They aim to reframe the threat to net neutrality as more than a conflict between digital leviathans like Google and internet service providers like Comcast but as part of a much wider project to commercialize the public sphere and undermine the free speech essential for democracy. Readers will come away with a better understanding of the key concepts underpinning the net neutrality battle and rallying points for future action to democratize online communication.
In the post-9/11 era, media technologies have become increasingly inter twined with vertical power as airwaves, airports, air space, and orbit have been commandeered to support national security and ...defense. In this book, Lisa Parks develops the concept of vertical mediation to explore how audiovisual cultures enact and infer power relations far beyond the screen. Focusing on TV news, airport checkpoints, satellite imagery, and drone media, Parks demonstrates how “coverage” makes vertical space intelligible to global publics in new ways and powerfully reveals what is at stake in controlling it.

How institutions for Internet governance are emerging from the tension between the territorially bound nation-state and a transnational network society.
Coordinated Multiuser Communications provides for the first time a unified treatment of multiuser detection and multiuser decoding in a single volume. Many communications systems, such as cellular ...mobile radio and wireless local area networks, are subject to multiple-access interference, caused by a multitude of users sharing a common transmission medium. The performance of receiver systems in such cases can be greatly improved by the application of joint detection and decoding methods. Multiuser detection and decoding not only improve system reliability and capacity, they also simplify the problem of resource allocation. Coordinated Multiuser Communications provides the reader with tools for the design and analysis of joint detection and joint decoding methods. These methods are developed within a unified framework of linear multiple-access channels, which includes code-division multiple-access, multiple antenna channels and orthogonal frequency division multiple access. Emphasis is placed on practical implementation aspects and modern iterative processing techniques for systems both with, and without integrated error control coding. Focusing on the theory and practice of unifying accessing and transmission aspects of communications, this book is a valuable reference for students, researchers and practicing engineers.
As more Africans get online, information and communication technologies (ICTs) are increasingly hailed for their transformative potential. Yet, the fascination for the possibilities of promoting more ...inclusive forms of development in the information age have obfuscated the reality of the complex negotiations among political and economic actors who are seeking to use technology in their competition for power. Building on over ten years of research in Ethiopia, Iginio Gagliardone investigates the relationship between politics, development, and technological adoption in Africa's second most populous country and its largest recipient of development aid. The emphasis the book places on the 'technopolitics' of ICTs, and on their ability to embody and enact political goals, offers a strong and empirically grounded counter-argument to prevalent approaches to the study of technology and development that can be applied to other cases in Africa and beyond.
