Methods of Wireless Channel Modeling between Base Station and Moving Train

In the modern era, the provision of high-data rate wireless connection along railroad systems emerges as an essential component in fostering the development of infrastructure and driving overall economic growth. Due to this fact, attaining higher throughput appears to be an inevitable target for corresponding research facilities. Multiple ways of improving connection speed exist, including improvement of hardware and algorithms' efficiency, increasing of frequencies etc. One of the possible methods is dedicated to compensation of signal corruption which occurs during transmission based on knowledge about current or general wireless channel properties, which, to some precision, allows to compensate for frequency, phase, amplitude shift and signal delay. This article is devoted to the review of the channel modeling techniques appropriate for exploitation of 4G/5G and TSN in high-speed railway (HSR) scenarios.
