Abstract
The surveys that have been done on the use spectrum shows that some frequency bands are less busy compared with others. Cognitive radio has come to give the possibility to use the free band of a primary user for a secondary user. Confirmation of the presence of the primary user is typically performed by a spectrum sensing. A function of cognitive radio based on the ability to find unoccupied spectrum without interference. The cognitive radio spectrum sensing method considered in this work is Energy detection method based on the central limit theorem and the sensing performance of this scheme is quantified by the receiver operating characteristic (ROC), such as between the probability of detection versus the probability of false alarm. A simulation is carried out in the Matlab environment to show the relation between Pd and Pf with various SNR values.
