City leaders now confront a global competition for economic investment, and urban elites are casting about for strategies that promise to secure a share of this future of global economic growth. However, many of these strategies are largely symbolic in nature. City leaders, for example, compete for the Olympics so they can broadcast spectacular urban vistas to global television audiences. Officials pour public funds into tourist amenities to cultivate an image of vitality and renewal. But how are the local politics of urban redevelopment intertwined with the global politics of circulating vital urban images? Urban Communication brings together scholars from communication, cultural studies, and urban sociology to explore the symbolic dimensions of contemporary city-building, drawing on case studies from around the world.

This work focuses on the analysis and design of multiple element antennas (MEA) and their interaction with the propagation channel. In particular, attention is given to urban channels and how its information throughput, i.e. capacity, can be improved. With this in mind, this work extends an existing network model of the communication system in order to reduce computation time, investigates the communicational limits of MEA systems and proposes a synthesis method for capacity maximization.

Radical Communications explores unauthorized messages we see in the cities we live in and their impact on the construction of social reality. Michael Tsangaris treats the city as a text and examines the political slogans, graffiti, and street art of Athens as complex visual signs in an alternative communication system. He argues that the legitimacy, aesthetic value, and social acceptability of these expressions depend on the time, place, and social group or individual that interprets them. Finally, his analysis reveals the contradictory character of the contemporary city. It shows a city of social inequalities, cultural diversity, multinational encounters; of conflicts between age groups and political, economic, and epidemic crises; a city of one-dimensional thinking, apathy, and consumer fetishism but also a city that aspires to the dream of a better society and holds utopian promise.

Radio Propagation and Adaptive Antennas for Wireless Communication Networks, 2nd Edition, presents a comprehensive overview of wireless communication system design, including the latest updates to considerations of over-the-terrain, atmospheric, and ionospheric communication channels. New features include the latest experimentally-verified stochastic approach, based on several multi-parametric models; all-new chapters on wireless network fundamentals, advanced technologies, and current and modern multiple access networks; and helpful problem sets at the conclusion of each chapter to enhance clarity. The volume’s emphasis remains on a thorough examination of the role of obstructions on the corresponding propagation phenomena that influence the transmission of radio signals through line-of-sight (LOS) and non-line-of-sight (NLOS) propagation conditions along the radio path between the transmitter and the receiver antennas—and how adaptive antennas, used at the link terminals, can be used to minimize the deleterious effects of such obstructions. With its focus on 3G, 4G, MIMO, and the latest wireless technologies, Radio Propagation and Adaptive Antennas for Wireless Communication Networks represents an invaluable resource to topics critical to the design of contemporary wireless communication systems. Explores novel wireless networks beyond 3G, and advanced 4G technologies, such as MIMO, via propagation phenomena and the fundamentals of adapted antenna usage. Explains how adaptive antennas can improve GoS and QoS for any wireless channel, with specific examples and applications in land, aircraft and satellite communications. Introduces new stochastic approach based on several multi-parametric models describing various terrestrial scenarios, which have been experimentally verified in different environmental conditions New chapters on fundamentals of wireless networks, cellular and non-cellular, multiple access networks, new applications of adaptive antennas for positioning, and localization of subscribers Includes the addition of problem sets at the end of chapters describing fundamental aspects of wireless communication and antennas.

This edition features a wealth of new material on urban warfare, including a computer simulation of EW architecture alternatives for land-based forces based on urban constraints. It also includes an expanded section on time-hopped spread spectrum communications, more details on modern communication system technologies such as CDMA and OFDM, and an in-depth discussion on sources of urban noise. This practical resource is focused on showing the reader how to design and build jammers specifically targeted at spread spectrum, anti-jam communications. Moreover, it gives assistance in evaluating the expected performance of jamming systems against modern communications systems, and discover the best waveform to use to counter communication systems designed to be effective in jamming environments. While mathematical derivations in general are avoided, the book presents error rate performance equations for most modern digital anti-jam communication systems
