The Roles of Ultra Wideband in Cognitive Networks

Abstract

Cognitive radio is a recent concept that is expected to lead wireless communications to a new era. A proper candidate for the physical layer implementation of cognitive radio networks is ultra wideband (UWB), because UWB is highly competent in satisfying many basic requirements of cognitive radio. Beside this, UWB can also provide various kinds of supportive uses to cognitive radio systems that are realized by means of other wireless technologies. In this paper, a number of possible roles that UWB can take in cognitive networks are discussed in detail.
