Underground Cooperative Spectrum Sensing Based on Neural Network

Aimed at problems in mine wireless communication,this paper pointed out that single-node spectrum sensing of cognitive radio could not suit problems such as multipath fading and noise in underground,and applying multi nodes' cooperative spectrum sensing to the coal mine underground was proposed.With complex parameters in the mine,in this paper,combined neural network with strong adaptation,the design idea of cooperative spectrum sensing model based on neural network was discussed.Through MATLAB simulation,it was proved that its detection performance was better than AND,OR criteria.
