Underground Time-Hopping Ultra Wideband Wireless Communication System Based on Simulink

Ultra wideband technology has the advantages of high transmission rate,low emissive power and simple system structure,which is suitable for wireless communication in coal mine.In Simulink,a communication model of Time-hopping ultra wideband based on multiple access technology is established.Combined with the simulation results,the paper studies each part of the model.It focuses on the problems of multi-user data sending and synchronization acquisition of correlation reception.The results verify the feasibility of the system in the coal mine.
