Given recent advances in High Speed Trains (HSTs), there has been an extensive amount of research dedicated to implementing Long Term Evolution cellular communications for Railways (LTE-R) with respect to next generation wireless communication systems. Achieving a reliable coverage inside a tunnel environment has always been a challenging task. Leaky Coaxial Cables (LCXs) have been shown to provide a uniform signal coverage in indoor environments such as offices and malls, and have been experimentally evaluated for tunnel environments. In this paper we model the HST channel inside a tunnel employing LCX and considering the classical two-ray propagation model. We analyze the LTE-R communication system utilizing the LCX and determine small-scale fading characteristics of the channel. Our channel model also takes into account the large Doppler shift caused by the high velocity of the trains. In addition to the proposed channel model, a dynamic Rician K-factor function depending on the reflector's material properties is also derived. The proposed channel is characterized by its bit error rate (BER) performance.
