Spectrum Sensing for Half and Full-Duplex Cognitive Radio,nt. This procedure means that the CR can only operate in a Half-Duplex (HD) mode. Recently, many works have been proposed in order to attend the Full-Duplex (FD) mode. In other words, the Spectrum Sensing should be performed while SU is being active. Our work deals with the HD and FD of CR. First, w

Reconfigurable MIMO Antennas for Cognitive Radios,ommunication standards. The front end of a CR consists of a sensing antenna for spectrum scanning and a reconfigurable antenna or reconfigurable multiple-input-multiple-output (MIMO) antenna system for communication over several frequency bands. Reconfigurable antennas in CR applications are used to
