摘要
针对目前矿井下无线通信状况,提出了把Chirp-超宽带无线通信技术应用到矿井下的设想。介绍了线性调频超宽带无线通信技术及其数字特性,得出相同的信噪比下Chirp-BOKUWB比2-PPMUWB有较小的误码率的结论,探讨了线性调频超宽带无线技术用于矿井下通信的可行性,并指出超宽带信号在矿井巷道中的传播特性研究对于设计矿井下UWB无线通信系统的重要性。
According to the analysis of the status of the coal mine underground wireless communication, a suggestion of using Chirp-UWB wireless communication system for coal mine underground communication was proposed. Chirp-UWB wireless communi- cation technology and its digital characteristics were introduced. And a conclusion was gained： Chirp-BOK UWB signals have lower error rate than 2-PPM UWB signals at the same SNR condition. The feasibility in underground Chirp-UWB system was discussed. It was obviously necessary to make the research of the propagation characteristic of UWB in coal mine tunnel for adopting UWB wireless communication system in coal mine underground.
