The increasing interest that has been drawn to the LTE system used in High-Speed Railway therefore requires measurements and analysis of wideband mobile channel for train-ground communications. Based on the hierarchical twohop network structure, extensive and practical measurements are performed on Harbin-Dalian passenger dedicated line with a speed up to 370 km/h by the approval of the Ministry of Railways of China. This paper first presents comprehensive analyzed results of the statistical channel properties, including both the large-scale and small-scale fading parameters. The proposed path loss model is applicable to high-speed railway plain scenarios and benefits the link budget of the LTE system. In particular, channel impulse response, power delay profile, the delay spread, the number of paths and delay-Doppler spectrum are extracted, evaluated and reported. All these results promote the evaluation and verification of wireless wideband communications on the high-peed railway.
