The design principle for cognitive radio (CR) networks regards the cognitive radio users as visitors in the spectrum they occupy. This necessitates efficient spectrum management functionalities to occupy idle channels without causing interference with the primary users, and leave these channels when primary user activity is detected. The successful operation of these principles relies on the CR users’ ability to be aware of their surroundings, which is accomplished through spectrum sensing solutions.
