摘要: 文中提出了一种基于信任的合作频谱感知框架.通过本地感知差异、感知位置因素、控制信道条件为参与频谱感知的用户建立信任, 准确地权重决策中心的单用户感知信息.仿真结果表明, 在一定虚警概率的约束条件下, 该框架应用于具体模型时具有较低的漏检概率.Abstract: A trsut based cooperative spectrum sensing framework is proposed to establish trust for each user throuh local sensing difference, sensing location factors, control channel conditions, which can accurately weight a single user's information at the decision-making center.Simulation results show that while applying to concrete models the proposed framework has lower missed detection probability within a certain false alarm probability.
