Abstract: 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.
