TL;DR: Wireless coverage based on massive MIMO for railway stations and train cars is proposed to fulfill the requirement of high-data-rate and high spectrum efficiency and the technical challenges brought by the massive M IMO technique are discussed.

TL;DR: It is found that the viaduct height H, together with the number of surrounding scatterers, significantly affects the small- and large-scale channel parameters, and the Suzuki distribution is found to offer a good fit for the composite multipath/shadowing channels.

TL;DR: In this paper, an empirical path loss model was proposed for high-speed railway viaduct scenarios, considering the influences of the height H and base station antenna relative height h, which are not well-covered by existing large-scale models.

TL;DR: Measurements of the propagation channel at 930 MHz conducted along the “Zhengzhou-Xi'an” HSR of China are presented, to characterize the small-scale fading behavior of rail-cutting scenarios as a function of the geometry of cuttings, including crown width and bottom width.

TL;DR: In this paper, the Ricean distribution was used to analyze the radio wave propagation in a high-speed railway cutting scenario, derived from 930 MHz measurements taken along the Zhengzhou-Xi'an high- speed railway of China.
