英文摘要	In this paper, a recently conducted measurement campaign for High-Speed-Train (HST) channels is introduced where the down-link signals of in-service Long Time Evolution-Advanced (LTE-A) networks deployed along a HST railway between Beijing to Shanghai were acquired. The channel impulse responses (CIRs) are extracted from the received Cell-specific Reference Signals (CRSs). The results show that, most of the channels contain a delay trajectory corresponding to a line-of-sight (LoS) path. The geometry parameters such as the train speed and the minimal distance between the transmitter and the receiver are extracted from the delay trajectories. Furthermore, path loss characteristics along the trajectories are investigated and compared with the model extracted for the Universal Mobile Telecommunications System (UMTS). ? 2016 IEEE.; EI
