Ultra-Wideband Wireless Communications and Networks
內容描述
Description
Ultra-wideband (UWB) technology has great potential for applications in
wireless communications, radar and location. It has many benefits due to its
ultra-wideband nature, which include high data rate, less path loss and better
immunity to multipath propagation, availability of low-cost transceivers, low
transmit power and low interference. Despite R&D results so far
demonstrating that UWB radio is a promising solution for high-rate short-range
wireless communications, further extensive investigation is necessary towards
developing effective and efficient UWB communication systems and UWB
technology.
Ultra-wideband Wireless Communications and Networks explores both
the fundamental aspects and the more advanced topics of networks and
applications. Challenges and up-to-date technical progress in the field are
presented, with timely reporting of results from cutting-edge research and
state-of-the-art technology in UWB wireless communications.
Unique focus on UWB wireless communications rather than previously
covered UWB radar aspects.
Topics include: radio propagation and large scale variations, pulse
propagation and channel modelling, MIMO (Multiple Input – Multiple Output)
RF subsystems and ad hoc networks.
Features a wealth of tables, illustrations and photographs.
This book is aimed at professionals wishing to enhance their knowledge of
UWB wireless communications systems for short range communications. It will
also appeal to senior undergraduate and graduate students who require
information on the key topics in this area.
