Abstract
Various radio communication systems are used in railway systems such as Communications Based Train Control (CBTC) systems, passenger information service systems, wireless sensor networks, etc. Designing or evaluating work to build radio communication systems used on railways is time consuming and expensive, given today's environment. Thus, as a contribution to this work, authors have developed a simulation system to calculate transmission characteristics (receiving power, strength of interferences, bit error rates, frame loss rates, delays, etc.) with considering the railway-specific environment and usage. And, the authors have also proposed evaluation method for stability of radio communication based train control systems by using the simulation system. This paper describes simulation model and major features of our simulator. And this paper also reports some examples of simulation results.
