Spectrum sensing is one of the crucial aspects in Cognitive Radio (CR). Fast and accurate spectrum opportunity detection provides interference avoidance to other/licensed users. At the same time, it offers more efficient spectrum utilization by providing accurate sensing information as an input to the intelligent dynamic resource allocation process. Wideband spectrum sensing has been introduced due...
Cognitive Radio (CR) introduces the idea of system awareness and intelligent adaptability in order to provide more efficient spectrum utilization especially in spectrum scarcity environment, which is happening in wireless communications. One of the key CR functionalities is the spectrum sensing, which allows CRs to monitor radio environment and detect unused spectrum. A fast and accurate detection...
