Channel Measurement-based Ray-tracing Analysis for High Speed Railway Scenario at 800MHz

Abstract

The analysis of channel measurement based ray-tracing (RT) simulation nowadays is considered as one of the most effective in solving traffic railway communication. In order to handle the increasing capacity demand for higher transmission capabilities, the railway communication system should be support by high data rate conectivity and feasible in many areas included urban area. The channel characteristic for railway scenario are explored by RT analysis method in the simulation at 800 MHz with 20 MHz bandwidth. Also most straightforward way to increase capacity is to add more bandwidth. The scenario for high speed railway (HSR) are modeling in urban area. However due to channel information parameters are extracted and incorporated into a 3GPP-like random channel generator. Well to analysis the channel mesurement depend on ray-tracing for HSR can be adjusted with the channel information on the area.
