Description: Spectrum sensing technology is the key technology of the cognitive radio(CR),the reliability and accuracy of the spectrum detection decides whether it will affect the normal communication of the main users and the utilization of spectrum of the cognitive users.Among the many methods of spectrum detection,energy detection is a commonly used method.However,in practice,the uncertainty of noise interference makes the setting of the threshold difficult,causing an interruption of the communication of the main use
