Abstract

The identification of the primary user is one of the most important issues in the spectrum sensing process for the cognitive radio networks. In order to improve the detection performance of spectrum sensing networks, doublethreshold energy detection based cooperative spectrum algorithm is proposed. Soft combination of the observed energy value from different cognitive radio users is investigated to solve the sensing failure problem in conventional twothreshold energy detection. We further propose to combine the intermediate energy values only when the sensing failure problem occurs. Results show that the proposed method achieves a good tradeoff between sensing performance and communication overhead.
