集群协同频谱感知的能量效率

发布时间：2021-11-07 22:26

　　本研究工作通过集群协作频谱感知（CCSS）创新技术分析了能效问题的解决方案。通过协调多个集群组成一个集群组,使用一个具有感知信道最高移动能力特征的中心集群组,协作集群合作频谱感知能量消耗减少进行这项研究的主要目的。本研究的重点在于研究人员的技术创新成果和对社会的积极环境影响。系统模型的设计是成功完成的研究人员描述信息传输到时间槽,从感知信息作为源通过簇首转移到认知中继在时隙T1和融合中心进行决策,然后反馈被发送给源以在时隙T2期间发生响应。所使用的方法基于系统模型设计,定量数学分析和matlab模拟来确定根据研究问题而降低能耗的性能。根据系统模型设计的结果仿真描述了检测概率和与能耗有关的虚警概率。仿真结果表明研究目标的成功实现
