摘要
总结了我国煤矿通信 ,尤其是井下移动通信存在的问题。指出扩频通信具有抗干扰能力强、易于实现码分多址等优点 ,特别适合煤矿通信。论述扩频通信技术在煤矿井下移动通信中的应用前景 。
The existing problems of coal mine communication, especially of the underground mobile communication are summarized in the paper. It is also pointed out that spread spectrum communication has advantages of strong in anti interference and easy to realize CDMA, and it is particularly adopted for coal mine communication. The paper discusses the applying foreground of the spread spectrum communication technology in mobile communication used in coal mine, and shows the feasible and practical program.
