This paper introduces spectrum sensing technology based on energy detection in cognitive radio .The detection probability and false alarm probability are discussed based on the Gauss and Rayleigh fading channels.By MATLAB simulation, the theory and the simulation’ s curve were deserved.The re-sults show that energy detection method is an effective spectrum sensing method of the determined noise situation.
