Analysis and Simulation of the Cooperative Spectrum Sensing Algorithm Based on Twice Detection
For the low accuracy of the spectrum sensing of the single node,this paper discusses several popular cooperative spectrum sensing technology.It also proposes a clustering double threshold cooperative spectrum sensing algorithm does two threshold detection based on the double threshold cooperative spectrum sensing algorithm.This algorithm applies or data fusion rule to realize the combination of the data among clusters on the basis of the improvement of the double threshold detection technology.The simulation results show that this algorithm can effectively reduce false alarm rate and undetected rate,and it can improve the overall detection performance.
