Abstract
This paper focuses on the shadow fading characteristic in viaduct scenario of the High-speed Railway. Measurement is done on Beijing to Shanghai High-speed Railway. Based on the measurement data, distribution and autocorrelation of the shadow fading are researched. Statistical values of the shadow fading standard deviation and the decorrelation distance are analyzed. It is shown that the lognormal distribution suits most groups of the measurement data well. Evaluation of the exponential shadow fading autocorrelation model and the double exponential shadow fading autocorrelation model are made in terms of mean error, standard deviation and correlation coefficient of the residuals between the models and the measurement data. Simulation results show better performance of the double exponential model compared with the exponential model.
