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...
Multiple-input multiple-output (MIMO) systems can achieve high capacity with applying space division multiple access benefits. By using channel state information at BS/MS we can remove inter user interference by applying beam forming. An important challenge at multi user (MU) systems is how design transmitting vector with respect to inter user interference. Capacity problem optimization, maximizing...
