Interference research and analysis of LTE-R

GSM-R system is a widely used means of railway communication, its commercial success are fully explained that GSM-R system has maturity and reliability. However, with the continuous development of rail transport, GSM-R has shown many limitations in high-speed, high-quality transmission. Therefore, the UIC has been basically confirmed LTE as the next generation railway wireless communication technology. The paper mainly studies the TD-LTE interference problems within the system and the system for GSM-R communications system coexistence interference. It also summarizes the types and causes of interference generated and gives a number of measures to reduce the interference by analyzing the principle of LTE technology and signal characteristics.
