Abstract

In this paper, we analyze performances for BLER and spectral efficiency in a high speed train (HST) system. The HST scenario is one of 5G mobile communication services. The performance analysis is evaluated in accordance with DM-RS mapping for channel estimation. DM-RS mapping is associated with high Doppler and frequency flat channel properties of the HST scenario. The performance results show that DM-RS in new radio (NR) satisfies the performance requirement of HST in ITU-R and a modified DM-RS mapping can be more efficient in HST channel properties.
