Study on the propagation scenario classification of the High-speed Railway GSM-R System based on GIS

This paper focus on the problem of the classification of the propagation scenario of the High-speed Railway GSM-R System. Common scenarios and particular scenarios are classified and discussed. For the conventional classified method cannot work well in the study on the propagation characteristics of the High-speed Railway GSM-R System, this paper proposes a scenario classification method based on GIS. And the definition method of the particular scenarios, which are model tuning and deterministic analysis, are discussed in detail. The methods proposed in this paper provide a feasible way to classify and define the propagation scenario of the High-speed Railway GSM-R System more preciously.
