Cooperative Spectrum Sensing of Cognitive Network Based on Rician Channel

This paper derives the model of local spectrum sensing and cooperative spectrum sensing over Rician channel,and makes simulation.The results suggest that the sensing performance of local spectrum sensing over Rician channel is not so far as the performance over the AWGN,then with the increase of secondary users,the performance of cooperative spectrum sensing may improve sensing performance significantly,and will be better then the circumstance over the AWGN when the number of the secondary users is big enough.
