基于线性加权的频谱感知算法研究综述
Research on spectrum sensing algorithm based on linear weighting
摘要
Abstract
The spectrum holes can be found with the spectrum sensing technology according to the peripheral spectrum re⁃sources detected by the cognitive users,which can dynamically access the frequency band,and improve the utilization of the spectrum resource. Multi⁃node cooperative spectrum sensing can overcome the shortcomings that may occur when a single node is used for detection,so cooperative spectrum sensing technology has been developed rapidly. The weighted algorithm in the co⁃operative spectrum sensing technology is studied in this paper,in which different weight is distributed to each user,and then the simulation is carried out for the linear weighted algorithm. The final detected results were obtained on the basis of the im⁃provement of the algorithm.关键词
