Abstract

The coal mine communication technology is relatively backward in our country, the spread spectrum communication technology is put forward. Its strong anti-interference ability and the advantages of easy implementation code division multiple access fill the deficiency of the coal mine communication technology. Points out that the domestic spread spectrum communication technology feasible scheme: both leakage cable combined and medium frequency induction spread spectrum communication constitute a coal mine communication network.
