Abstract :
We address the problem of primary user detection in cognitive radio networks. The performance of cooperative spectrum sensing with equal gain combination over Nakagami channels is investigated in this paper, and the series form of detection probability is obtained. In the numerical results, the correctness of the theoretical analysis results is validated, and the detection performances with different parameters are shown.
