摘要：

Cognitive Radio (CR) technology is being recognized as an efficient method in dealing with the scare spectrum resources, the spectrum detection is one of the important steps in CR, and the cooperative spectrum detection is popular because of its good detection ability. Based on a brief analysis and contrast of the "soft decision" and "hard decision" algorithms, the double threshold spectrum sensing algorithm was proposed in this paper which can ensure the detection precision, and reduce the measurement of transmitted data meanwhile. Theory analysis and simulation results show that the novel algorithm can enhance the detection probability and reduce the detection time.
