Abstract

In high speed railway environment, the LTE system performance evaluation is of vital importance due to complexity of radio propagation scenario and high mobility. In this paper, the Hardware-in-the-Loop (HIL) simulation platform is built, which consists of radio channel emulator, LTE core network and so on. Based on this platform, the LTE system performance is tested under Rician channel with different parameters, such as the K-factor, the angle between the line-of-sight (LOS) and train’s velocity. Finally, it is concluded that the LTE system performance degrades with the increase of moving speed, and the degree of degradation is related to the K-factor and the angle between the LOS path and velocity.
