Abstract

Single Frequency Network (SFN) is considered as a vital deployment method in High Speed Train (HST) scenario. HST channel model is of much importance to LTE performance assessment. And SFN channel models are non-stationary. Since the train moves fast, the impact of Doppler rises significantly. The consideration of the effect of Doppler shift in SFN scenario is of much difference from in traditional stationary channels. In this paper, we build a link level simulation system and evaluate the performance of TD-LTE system with single-tap and two-tap SFN High Speed Train (HST) channel models without frequency compensation. The results show that when the Doppler shift exceeds 1000 Hz, the performance degrades much more obviously. Additionally, the absolute value of Doppler shift has great influence on TD-LTE system and the impact of Doppler shift variation on the system performance is not obvious. This paper provides reference for the design of next generation railway mobile communication system and lay a foundation for the LTE high-speed adaptability research.
