Cognitive Radio is the Future of RF/Wireless, this Volume is Your Passport to that Future!Few developments have created as much excitement among RF/wireless designers and engineers as cognitive radio. It seems almost magical—a wireless network that is truly “aware” of its operating environment and adjusts its operating conditions (such as frequency and transmitter output power) to maintain desired communications and overcome interference. A solid working knowledge of cognitive radio concepts, principles, and applications will soon be essential knowledge for all RF/wireless professionals.
Answering this need, Dr. Bruce Fette has gathered together several experts on cognitive radio to shape this comprehensive guide. It begins with the foundations of cognitive and software-defined radio, and goes on to cover protocols employed by cognitive radio, as well as, hardware and software architectures, spectrum efficiency considerations, regulatory issues, and current application. Cutting-edge cognitive radio research is also considered with an emphasis on the future growth and progress of this technology.
With this volume, you’ll have the background to master and apply today’s cognitive radio technologies and understand tomorrow’s developments in the field.
KEY FEATURES
*Discusses the spectrum and network “awareness” capabilities of cognitive radio systems
*Explains special capabilities of cognitive radio systems, such as position awareness
*Describes cognitive radio network properties, protocols, and optimization techniques
*Explores the various speech and image processing services available with cognitive radio
Synopsis
Cognitive radio technology is a smarter, faster, and more efficient way to transmit information to and from fixed, mobile, other wireless communication devices. Cognitive radio builds upon software-defined radio technology. A cognitive radio system is 'aware' of its operating environment and automatically adjusts itself to maintain desired communications—it’s like having a trained operator ‘inside’ the radio making constant adjustments for maximum performance. Operating frequency, power output, antenna orientation/beamwidth, modulation, and transmitter bandwidth are just a few of the operating parameters that can automatically be adjusted “on the fly” in a cognitive radio system.
Fette has constructed a cutting-edge volume that hits all of the important issues including research, management, and support. Cognitive techniques will be discussed such as position and network awareness, infrastructure and physical and link layer concerns. Though still a nascent technology, cognitive radio is being pushed by the US military and for mission-critical civilian communications (such as emergency and public safety services).
*The first book on a revolutionary technology that will be critical to military, emergency, and public safety communications
*A multi-contributed volume written by the leaders in this exciting new area
*Describes the location-determination capabilities of cognitive radio (the precise location of all units in a cognitive radio network can be determined in real time)
