Abstract In order to obtain accurate characteristics of wireless channels in the viaduct area of China, a channel measurement was taken in a railway viaduct scenario of the Zhengzhou-Xi’an passenger dedicated line with a bandwidth of 50 MHz at 2.35 GHz. The single-slope log-distance model is used to analyze the path-loss (PL), and the distribution of shadow fading (SF) is obtained by statistical methods, which shows that the normal distribution fits the samples well. Ricean K-factor is analyzed by the method of moments, and the variation of K-factor is given along the measured route. Small scale such as delay spread and Doppler behavior are parameterized. Based on empirical channel measurement, this paper can provide parameters for the evaluation and simulation work on viaduct scenarios of high-speed railway.
