Paper Abstract

Cognitive radio is a kind of intelligent and spectrum sharing technology for improving the utilization of spectrum. It can detect primary user by sensing empty spectrum bands. Due to shadowing and multi-path fading, the reliability of single terminal detection is low. Information fusion algorithm based on collaborative spectrum sensing can improve the sensing performance significantly. In this paper, a high performance information fusion algorithm has been studied on the basis of analyzing several classic fusion algorithms. We drive the expression for the probability of the detection and the falsealarm for this fusion algorithm. Simulating results indicate that the fusion algorithm presented in this paper achieves better detection performance than traditional fusion algorithms.
