摘　　要：对认知无线电的频谱感知技术进行分析,同时结合煤矿巷道环境特点提出煤矿巷道认知无线电感知模型。提出的单节点采用能量检测和循环平稳特征检测联合算法,既弥补了能量检测在低信噪比下检测概率低的缺点,又改善了循环平稳特征检测需要较长时间的问题。The spectrum sensing technology of cognitive radio is analyzed, and the cognitive radio sensing model in coal mine tunnel is established combined with the characteristics of the coal mine tunnel environment. The joint algorithm of energy detection and eyclostationary feature detection is adopted to the situation of single node, which makes up the shortcoming that the energy detection has a low detection probability in low SNR and improves the problem that cyelostationary feature detection needs longer time.

关 键 词：认知无线电 巷道通信 频谱感知 能量检测 循环特征检测
