Abstract
Cooperative Spectrum Sensing (CSS) is the critical component of the cognitive radio technology, which could relieve the shortage of spectrum recourses. The double threshold based CSS scheme was adopted to deal with the unreliability when the original energy value locates around the traditional single threshold. We utilize the dynamic double threshold based energy detection scheme, in which it can adjust the double threshold properly to respond the transformation of channel condition. This proposed dynamic double threshold based scheme could be verified by analyzing the formula and simulation, and it achieves the better performance compared with classical double threshold based CSS scheme.
