Abstract

The multi-path fading could be resisted in mine tunnels by using MIMO technology, but transmittal power of wireless communication equipment in tunnels must be confined as a result of preventing explosion. A novel power allocation algorithm of confined transmit power is proposed to apply coal mine tunnels based on existing scheme. It could implement transmit average total power minimization and optimal allocation on confined each antenna power. The simulation results showed that the computation complexity of new proposed algorithm is reduced under the satisfying target bit error rate as well as total transmit power while limitation of per-antenna peak power, and the transmit efficiency would be increased significantly.
