杨维, 程时昕, 孙继平 · 煤炭学报：英文版 · 2000
For the purpose of making the best use of the mine frequency resource and realizing the instruction idea “to exchange bandwidth for distance” a W- CC)MA mine spread spectrum mobile communication scheme based on spread spectrum communication technique and the propagation characteristic of electromagnetic wave along laneways is proposed. The structure and make up of the system are studied and the working frequency and channels are assigned. Analysis indirates the scheme is a simple one that can fulfill the mine saying requirement.
