Radio Channel Research in Coal Mine Laneways

Abstract:

The transmission mode of wireless waves in coal mine tunnel is different from the mode in free space.The multipath propagation of wireless wave is severe in tunnel.As a result,the characteristics study of multipath propagation is very important to the design of wireless communication system in coal mine tunnel.After analyzing the multipath propagation attenuation in tunnel,the statistics of single frequency signal,narrowband signal and broadband signal are obtained.This is the foundation for the application of resisting multipath decline techniques.
