Enhancement of wireless channel performance using MIMO system in underground mine gallery

This paper studies the use of MIMO systems for underground mine communication. Measurement campaigns using two different type of antenna have been made in a real gold mine. Furthermore, the channel is characterized in terms of channel correlation, and capacity. Results suggest that in such scatter-rich environment, for LOS scenario the directional antennas have been shown to provide significant suppression of multipath and a corresponding increase in the correlation that consequently decrease the channel capacity.
