Coding for Wireless Channels is an accessible introduction to the theoretical foundations of modern coding theory, with applications to wireless transmission systems. State-of-the-art coding theory is explained using soft (maximum-likelihood) decoding rather than algebraic decoding. Convolutional codes, trellis-coded modulation, turbo codes, and low-density parity-check (LDPC) codes are also covered, with specific reference to the graphical structures through which they can be described and decoded (trellises and factor graphs). A special section is devoted to...

Examining modulation, coding and multiple access techniques, the book is divided into two major sections to cover these functions....

Why pay high prices for a shop to install or maintain your car stereo when you can have the satisfaction of doing it better yourself?

Auto Audio: Choosing, Installing, and Maintaining Car Stereo Systems, Second Edition, by Andrew Yoder, provides all the information you need to supercharge your ride with top-quality speakers, amplifiers, head units, equalizers, signal processors, changers and antennas -- not to mention filters and crossovers, wire, cabling, connectors and transmitters. And once your system is in,...

Access to Mobile Services focuses on methods for accessing broadcast based M-services from multiple wireless channels. This book presents a novel infrastructure that provides a multi-channel broadcast framework for mobile users to effectively discover and access composite M-services. Multi-channel algorithms are proposed for efficiently accessing composite services.

Access to Mobile Services provides an in-depth survey of wireless data access and motivates the need to treat mobile services differently. A wireless adaptation of Service Oriented Architecture (SOA) is also covered.

As World War II drew to a close and radio news was popularized through overseas broadcasting, journalists and dramatists began to build upon the unprecedented success of war reporting on the radio by creating audio documentaries. Focusing particularly on the work of radio luminaries such as Edward R. Murrow, Fred Friendly, Norman Corwin, and Erik Barnouw, "Radio Utopia: Postwar Audio Documentary in the Public Interest" traces this crucial phase in American radio history, significant not only for its timing immediately before television, but also because it bridges the gap between the end...

Radio Frequency IDentification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. An RFID tag is a small object that can be attached to

or incorporated into a product, animal or person. An RFID tag contains an antenna to enable it to receive and respond to Radio-Frequency (RF) queries from an RFID reader or interrogator. Passive tags require no internal power source, whereas active tags require a power source.

As of today (2006), the concepts of ubiquitous computing and ambient...
