Cognitive radio technology is a novel and effective approach to improve utilization of the precious radio spectrum. Spectrum sensing is one of the essential mechanisms for Cognitive Radio (CR) and various sensing techniques are used by the secondary users to scan the licensed spectrum band of the Primary Radio (PR) users to determine the spectrum holes. These can be intelligently used by the secondary users also referred to as CR users, for their own transmission without causing interference to the PR users.
