Line of sight MIMO-UWB short range communication in underground mine tunnel

This paper deals with experimental results of Multiple-Input Multiple-Output (MIMO)-Ultra Wide Band (UWB) system. Measurement campaigns under line-of-sight (LOS) scenario using two different antenna configurations have been made in underground mine environment. Results, suggest that the channel transfer matrix depends not only on the propagation environment but also on the MIMO array configuration. In fact, the important point is to decide which array topology is best in terms of maximizing capacity. The optimal MIMO system arrangement is selected based on main channel parameters such as channel correlation and capacity.
