Novel Double Threshold Based Energy Detector for Spectrum Sensing

The double threshold energy detector has attracted wide attention because of its low detection complexity. However, this comes at the expense of some sensing performance loss. Motivated by this, our paper proposes a novel double threshold detection method. Where maximum and minimum sensing threshold is redesigned and analyzed therein. Additionally, it is expanded to cooperative spectrum sensing for the issue of the hidden terminal. Simulation results verify the validity of the scheme.
