Efficient spectrum management has today become a necessity. In cognitive radio networks CRN; Spectrum sensing aims to detect the unused spectrum to use it more efficiently; it allows secondary users (SU) to detect the presence or absence of primary users (PU) in licensed bands to use it temporary without interfering with PU signal transmission. In order to use the Radio spectrum dynamically and ensure a good quality of service QoS to both PU and SU; many detection methods have been proposed such as energy detection, cyclostationary based sensing and matched filter detection. In this poster, some spectrum sensing techniques are …
