A Cooperative Double-Threshold Energy Detection Algorithm in Cognitive Radio Systems
Jinbo Wu, Tao Luo, Jianfeng Li, Guangxin Yue · 2009
As is well-known, cooperation among cognitive users can improve the accuracy of spectrum detection in cognitive radio systems. In this paper, based on OR-rule, a cooperative double-threshold energy detection algorithm is proposed. Theoretical analysis and simulation results indicate that this strategy can improve the spectrum detection probability significantly.
