Abstract: |
Cognitive radio technology is a kind of intelligent spectrum sharing technology which can improve the utilization of spectrum resources, and it is the key and precondition of cognitive radio. Due to spectrum sensing technology itself limitations and the influence of hidden terminal and multi-path fading, single terminal detection is not so credible .But cooperative spectrum sensing can improve the spectrum perception efficiency. Based on the cooperative spectrum sensing, this paper proposes a kind of data fusion algorithm based on clustering cooperative spectrum sensing. Computer simulation results indicate that the algorithm can not only adapt to different regional environment, improve the detection accuracy, but also can reduce public channel occupancy rate, increase overall detection efficiency.
