Reproducing High-Speed Train Channel with the Multi-Probe Anechoic Chamber Method

High-speed train (HST) communication has become one of the standard communication scenarios, due to the rapid development of HST techniques. Many researchers have been focusing on it recently. This paper discusses the reproduction of HST channels in laboratory environments, via carrying out an over-the-air (OTA) testing campaign. We conducted measurement work in practical railway environments, and established a non-stationary geometry-based stochastic channel model according to the measured data. Moreover, an OTA testing campaign was performed based on the multi-probe anechoic chamber (MPAC) method. The testing results suggest that great matches have been achieved between the indicators recorded in laboratory and the measured ones in railway environment, e.g., reference signal receiving power (RSRP), Doppler frequency spectrum (DFS) and power delay profile (PDP).
