煤矿巷道的频谱感知技术研究
首发时间:2011-09-02
摘要:针对煤矿巷道岔道多、巷道长的无线通信环境特点,本文提出一种基于簇的分布式合作频谱感知技术的算法。该算法选取每个巷道分支中SNR最大的节点作为簇头,簇间用分布式合作方式进行频谱感知。仿真结果表明,该算法不仅可以提高低信噪比下的检测概率,而且可以改善合作频谱感知的安全性。

Research on the mine tunnel's spectrum sensing network
Abstract:The mine consist of complex and long tunnels , to achieve the wireless communication in the mine tunnel , this paper proposed a kind of distributed cooperative spectrum sensing algorithm based on cluster. This algorithm select the node have the biggest SNR in every tunnel as the head, and the cluster work in the distributed cooperative way. The simulation result show that this algorithm not only can enhance the detected probability while enhance the SNR, but also can improve the net's security.
Keywords: mine tunnel cooperative spectrum sensing detected probability security
