Performance evaluation of energy detection based on non-cooperative spectrum sensing in cognitive radio network

The recent and rapid evolution of wireless technologies has led to a high demand in terms of resources. To solve the problem the idea of cognitive radio has been introduced to facilitate a good spectrum management and efficient use of the spectrum. In this article we present the spectrum sensing techniques which is a very important step in cognitive radio. The energy detection method used in this paper through the simulation result represented by the ROC curve (Receiver Operating Characteristic) shows that the performance of this method is simple and effective. In this paper, we conduct the performance evaluation of energy detection based on non-cooperative spectrum sensing. The simulation was made using the MATLAB based on the AWGN channel.
