Small-Scale Fading Analysis of the Vehicular-to-Vehicular Channel inside Tunnels

[EN] We present a small-scale fading analysis of the vehicular-to-vehicular (V2V) propagation channel at 5.9 GHz when both the transmitter (Tx) and the receiver (Rx) vehicles are inside a tunnel and are driving in the same direction. This analysis is based on channel measurements carried out at different tunnels under real road traffic conditions. The Rice distribution has been adopted to fit the empirical cumulative distribution function (CDF). A comparison of the K factor values inside and outside the tunnels shows differences in the small-scale fading behavior, with the K values derived from the measurements being lower inside the tunnels. Since there are so far few published results for these confined environments, the results obtained can be useful for the deployment of V2V communication systems inside tunnels.The authors want to thank J. A. Campuzano, D. Balaguer, and L. Morag on for their support during the measurement campaign, as well as B. Bernardo-Clemente and A. VilaJimenez for their support and assistance in the laboratory activities.
