Keywords: virtual coupling, channel model, train-to-train, characteristics, C-Band, communications.

Abstract

In this paper we give an overview of existing vehicle-to-vehicle channel models for the road and railway sector. Published models for the special application of train-totrain (T2T) communications are evaluated. Advantages and disadvantages of different modelling techniques are discussed to create a basis for a future T2T model. Based on the literature research the architecture for a broadband T2T channel model is presented. The model architecture is applied to different environments and the most important objects along the railway lines. A first examination of measurement data collected in the Roll2Rail project is discussed. The focus is on the received signal power, the latency and the influence of the different environments on those two measures. The measured scenarios include the environments station, open terrain, cuttings, walls, and tunnels.
