Abstract:
In this contribution, the On-body propagation measurements at 40 m underground mine gallery and their statistical analysis are presented. Monopole antennas were installed on the body in order to form three on-body channels, namely belt-chest, belt-wrist and belt-head. The channel parameters of a 2 × 2 Multiple-Input Multiple-Output (MIMO) On-body system are evaluated and compared to the single-input single-output (SISO) system parameters. It was shown that the RMS delay spread and capacity values of the MIMO channels are higher than those of the SISO channels. The average value of the Ricean K-factor shows little difference between the MIMO and SISO belt-chest measurements. The calculated capacity values for a constant signal to noise ratio (SNR) and those calculated at a constant transmitted power demonstrate that the propagation performance is significantly improved by using the MIMO compared to the conventional SISO scheme. Hence, MIMO technology is a suitable candidate for On-body underground communications.
