A Study on the Wireless Communication Using Microwave between Trains and Ground Facilities in High-speed Railway

摘要

In order to adapt to the new requests of the high-speed railway，thisDaper presents a microwave communication system between trains and ground tacilities．Concretely，the paper analyses propagation characteristics of the wirelesscommunication system，and compares several microwaves in different trequencybands．Secondly，factors which affect the Bit Error Rate at the receive antennaare discussed in detail，such as the velocity of the train and rainfall．Computersimulation indicates that the propagation characteristics can satisfied the requestsof the special communication．
