Ultra-wideband Communications: A Tutorial
Ultra-wideband (UWB) communications systems can be defined as wireless communications systems with very large fractional bandwidth. While long known as a radar technique, there are several factors currently motivating the use of UWB signals for communications. Potential benefits include better performance in severe multipath, low cost transceivers, large data rates (over short ranges) and mixed radar and communications functionality. Most importantly, however, UWB is getting attention because the FCC approved its unlicensed use in over 7 GHz of bandwidth.
