煤矿井下调频无线通信共信道干扰的研究

Research on Common-channel Interference in Underground FM Radio Communication

本文提出了煤矿井下适用的有线-无线相结合的移动通信方式,对该通信方式中存在的共信道干扰问题作了分析,在此基础上给出了三种通信方案,并通过实验予以验证。

A combined (wire-radio) mobile communication system used in underground mine is presented in this paper. The common-channel interference between FM signals in the system is discussed. Three methods to overcome the interference are suggested and realized through experiments.
