摘　　要：超宽带技术具有传输速率高,发射功率低,系统结构简单等优势,适用于煤矿井下无线传输。介绍了在Simulink环境下搭建运用多址接入技术的井下跳时超宽带通信模型,并结合仿真结果研究了该模型的各个部分,着重说明多用户数据的发送及相关接收的同步捕获问题。结果表明系统在煤矿井下的可行性。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 fea- sibility of the system in the coal mine.
