A self-contained guide to the state-of-the-art in cooperative communications and networking techniques for next generation cellular wireless systems, this comprehensive book provides a succinct understanding of the theory, fundamentals and techniques involved in achieving efficient cooperative wireless communications in cellular wireless networks. It consolidates the essential information, addressing both theoretical and practical aspects of cooperative communications and networking in the context of cellular design. This one-stop resource covers the basics of cooperative communications techniques for cellular systems, advanced transceiver design, relay-based cellular networks, and game-theoretic and micro-economic models for protocol design in cooperative cellular wireless networks. Details of ongoing standardization activities are also included. With contributions from experts in the field divided into five distinct sections, this easy-to-follow book delivers the background needed to develop and implement cooperative mechanisms for cellular wireless networks.

TheyÕve been listening for longer than you think. A new history reveals howÑand why. Wiretapping is nearly as old as electronic communications. Telegraph operators intercepted enemy messages during the Civil War. Law enforcement agencies were listening to private telephone calls as early as 1895. Communications firms have assisted government eavesdropping programs since the early twentieth centuryÑand they have spied on their own customers too. Such breaches of privacy once provoked outrage, but today most Americans have resigned themselves to constant electronic monitoring. How did we get from there to here? In The Listeners, Brian Hochman shows how the wiretap evolved from a specialized intelligence-gathering tool to a mundane fact of life. He explores the origins of wiretapping in military campaigns and criminal confidence games and tracks the use of telephone taps in the US governmentÕs wars on alcohol, communism, terrorism, and crime. While high-profile eavesdropping scandals fueled public debates about national security, crime control, and the rights and liberties of individuals, wiretapping became a routine surveillance tactic for private businesses and police agencies alike. From wayward lovers to foreign spies, from private detectives to public officials, and from the silver screen to the Supreme Court, The Listeners traces the long and surprising history of wiretapping and electronic eavesdropping in the United States. Along the way, Brian Hochman considers how earlier generations of Americans confronted threats to privacy that now seem more urgent than ever.

This book constitutes the refereed post-conference proceedings of the 12th International Conference on Wireless and Satellite Services, WiSATS 2021, held in Nanjing, China, in September 2020. Due to COVID-19 pandemic the conference was held virtually. The 79 full papers were carefully reviewed and selected from 140 submissions. The conference’s central theme is the means of using the wireless and satellite services directly to the user for personal communications, multimedia and location identification. The services enabled by WiSATS not only cover the requirements of an ordinary citizen but also provide personal and public services for global coverage communications as the applications of internet of things.

This volume offers essays on advances in the field of experimental social psychology. Topics discussed include: attitudes to high achievers; tactical communication and social interaction; social comparisons, legitimacy appraisals and group memberships; and stereotypes.

This book studies the vulnerability of wireless communications under line-of-sight (LoS) and non-LoS correlated fading environments. The authors theoretically and practically provide physical layer security analyses for several technologies and networks such as Fifth-Generation (5G) networks, Internet of Things (IoT) applications, and Non-orthogonal multiple access (NOMA). The authors have provided these under various practical scenarios, and developed theoretical aspects to validate their proposed applications. Presents physical layer security (PLS) under correlated fading environments, 5G wireless networks, and NOMA networks; Provides end-to-end analyses, combination of channel correlation and outdated CSI and their effects on PL; Includes contributions of PLS research written by global experts in academia and industry.
