Cognitive RadioCognitive Radio

According to Institute of Electrical and Electronic Engineers (IEEE)the cognitive radio is a radio transmitter/receiver that is designed tointelligently detect whether a particular segment of the radio spectrum iscurrently in use, and to jump into (or out of) the temporarily-unusedspectrum very rapidly, without interfering with the transmissions of otherusers
