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.
Index Terms-- Cognitive radio, cognitive node, impulse radio,
spectrum sensing, UWB-OFDM.
Cognitive radio is a novel concept for future wireless
communications, and it has been gaining significant interest
among the academia, industry, and regulatory bodies [1].
Cognitive radio provides a tempting solution to increasing
