矿井移动通信系统是矿井安全生产、抢险救灾的重要保障.为了提高矿井移动通信系统的可靠性和稳定性,文章提出将DS/FH混合扩频技术应用于矿井移动通信系统的方案,从理论上对DS/FH混合扩频技术进行了详细分析,在此基础上,基于Systemview建立了通信系统的仿真模型.仿真结果和系统的误码率特性分析证明了DS/FH混合扩频技术应用的可行性,为矿井移动通信的发展提供了重要的理论依据.%Mine mobile communication system is the important guarantee of mine safety production and emergency rescue and disaster relief. In order to improve the reliability and stability of mine mobile communication system, the paper put forward a scheme of applying DS/FH hybrid spread-spectrum communication in mine mobile communication system and theoretically made detailed analysis on DS/FH hybrid spread-spectrum communication technology. On the basis of the theory analysis, simulation model of the communication system was established based on Systemview. The simulation result and BER characteristics analysis proved the application feasibility of DS/FH hybrid spread-spectrum communication technology, which provides important theory basis for development of mine mobile communication.
