Capacity of the millimeter wave underground mine channel

In this paper, we are interested in the capacity computations of an underground mine channel in the millimeter wave band. A model of the channel based on the power delay profile (PDP) between transmitter and receiver is obtained from the channel measurements in the CANMET mine at the 70 m level. The channel model is examined under two scenarios, namely horn-horn and horn-omni antennas, in a line of sight (LOS) situation. The channel model is used to compute the capacity for two polarizations, namely HH and VV. The channel capacity of the model is compared with the channel capacity computed using the frequency response. The results show the pertinence of the model for the two measurement scenarios and for both polarizations. Results show that the differences in antennas and their polarisation play an important role in the design of millimeter wave radio systems.
