Abstract: Due to the significant growth of the wireless users number, and of the wireless
multimedia applications (which require an increasingly larger bandwidth), the radio
spectrum has become overloaded. The solution proposed by Joseph Mitola III, in order
to provide spectrum resources according to the user needs, was the Cognitive Radio
(CR), which allows dynamically using of the existing spectrum. In the recent years the
CR technology imposed itself as a very good solution to the increasing spectrum
utilization. This technology proposes the development of a new radio type – a cognitive
radio – endowed with intelligence that senses, shares, and uses the spectrum
opportunities (SOP) of the preexisting wireless networks, the channels that are not used
by the licensed users.
