Research of the Characteristics of Radio Wave Propagations around the High-Speed Railway

High-speed railway is the trend of our national railway. Research of the radio wave propagation is very important for the development of railway wireless communication system. In the paper, the simulation model of channel is formed using the theory of sine superposition. The parameters of the model are confirmed using the method of equidistance. Then, on the base of this channel, the characteristics of radio wave propagations of high-speed railway are analysed. At last, the relevant conclusions are given.
