Performances of Future Railway Mobile Communication Systems Under Indonesia Railway Channel Model

This paper provides the performances of future railway mobile communication systems (FRMCS) based on the fifth generation new radio (5G NR) which is soon replaced Global System for Mobile Communication-Railway (GSM-R) for high speed railway in Indonesia. This paper focuses on FRMCS performances evacuation affected by Doppler effect and interference of cellular GSM. To evaluate the FRMCS performances, Indonesia FRMCS channel model is proposed in this paper and obtained from a series of computer simulations with natural environment based on long-term local data parameters of Bandung and Jakarta. This paper also produces outage performances of FRMCS Indonesia channel model which is performed using simple channel coding and validated with bit error rate (BER). Finally, this paper has shown that FRMCS is promising as strong candidate of future high speed railway technology in Indonesia because of its reliability to overcome interference with cellular GSM and the Doppler effect that occurs at high speeds. Those results are expected to be the main reference in the development and implementation of FRMCS in Indonesia.
