  Abstract

One of the most important things in train control system is the train positioning. The train control center performs interval control, line transfer, and so on by train positioning. A new train positioning scheme is needed because train positioning exploits track circuit, RF tag(balise, PSM), tachometer, and so on but positioning accuracy is low (track circuit) or difficulty of installation and maintenance (RF tag). The positioning scheme by wireless communication has been actively studied, especially, 5G system serviced recently is superior to LTE with respect to positioning accuracy because of high sampling rage by broad bandwidth and dence baseband installation. Therefore we propose high speed train positioning schemes based on 5G and verify performance of the proposed schemes.
