In this paper, the power delay profile (PDP) and root mean square delay spread (RMS-DS) relationship is demonstrated to satisfy the LTE-M criteria for rectangular tunnel area at 1.8GHz. The leaky coaxial cable (LCX) was exploited as a transmitting antenna for both single-input single-output (SISO) and multi-input multiple-output (MIMO) systems. The effect of changing the received antenna (Rx) distance on the variation of received power using the Ray-Tracing Method is investigated. The reflected (NLOS) and line of sight (LOS) paths between the LCX and receiving antenna for both vertical and horizontal polarizations are deliberated and it was found that the horizontal polarized LCXs accomplish better performance than the vertically polarized cables used for both SISO and MIMO systems under tunnel environment. Furthermore, it was determined that the minimum distance between transmitting and receiving antennas can acquire higher received power.
