This has given rise to an 'artificial scarcity' of usable spectrum. Numerous studies have thus begun to examine how the licensed spectrum is actually used, with the goal of not only reforming the spectrum licensing(More)
This paper presents a genetic-algorithm driven, cognitive radio decision engine that determines the optimal radio transmission parameters for single and multicarrier systems. Determining the appropriate radio parameters given a dynamic wireless channel environment is the primary feature of cognitive radios for wireless communication systems. Genetic(More)
