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.)
