Research of application of cooperative communication to underground coal mine

WANG Tingting;XU Zhao;ZHANG Xiaoguang;School of Information and Electrical Engineering,China University of Mining and Technology;  
In view of complex electromagnetic wave propagation environment and outstanding multipath effects in coal mine,major anti-multipath methods of mine wireless communication were analyzed.According to the characteristics of cooperative communication technology,cooperative communication was proposed to apply to mine WMN communication system,and mine C-WMN communication system architecture was given.On the basis of geometry characteristics of several typical environments in mine,the corresponding modes of cooperative relay of C-WMN were analyzed.
