说明: 认知无线电技术的提出是为提高频谱利用率,而认知无线实现的关键技术是频谱感知,众所周知协作检测提高了衰落环境中认知用户系统检测的性能,该文章是基于协作检测提出新的检测方案,利用了双门限方法提高了系统性能,兼顾带宽有限和增强性能两个方面,是基于门限检测的协作检测性能优化的前提。对以后门限优化协作检测非常有用。(In this paper, we employ a double threshold method in energy detector to perform spectrum sensing, while a fusion center in the cognitive radio network collects the local decisions and observational values of the secondary users, and then makes the final decision to determine whether the primary user is absence or not. Simulation results will show that the spectrum sensing performance channels is improved significantly under the proposed scheme as opposed to the conventional method.)

层次分析法(Analytic Hierarchy Process,简称AHP)是将与决策总是有关的元素分解成目标、准则、方案等层次,在此基础之上进行定性和定量分析的决策方法。该方法是美国运筹学家匹茨堡大学教授萨蒂于20世纪70年代初,在为美国国防部研究"根据各个工业部门对国家福利的贡献大小而进行电力分配"课题时,应用网络系统理论和多目标综合评价方法,提出的一种层次权重决策分析方法。(AHP (Analytic Hierarchy Process, referred AHP) is always the element of the decision-making related to broken down into goals, guidelines, programs and other levels, on this basis for decision-making qualitative and quantitative analysis. This method is the U.S. Operations Research Professor at the University of Pittsburgh Satie early 1970s, the U.S. Department of Defense for research, " according to various industrial sectors contribution to national welfare and power sharing" topic, application network systems theory multi-objective and comprehensive evaluation methods, the right to propose a hierarchical weight decision analysis methods.)
