Study on MIMO Information Channel Volume in Mine Roadway

According to the application problems of MIMO (Multiple Input Multiple Output) in the special communication environment of the restricted non-free spac e in the underground mine, the multi factors affected to the MIMO information channel volume in the underground mine were studied and the simulation analysis was co nducted.The results showed that the MIMO applied to the mine roadway could have certain feasibility and practices.In order to have the max information channel volum e of the MIMO in the complicated environment of the underground mine, the particle swarm algorithm was applied to the theoretical formula of the MIMO antenna layout in the mine roadway.
