ABSTRACT

Aiming at the problem of poor signal reception in traditional railway trunking communication system, the research on cross-slot interference suppression method based on railway trunking communication system is carried out. The research on different suppression methods is combined with its advantages. The interference analysis of the cross-slots, and then the solution of the cross-slot interference suppression based on the isolation band is designed. By comparing the form of the test, it is tested that 5,000 signals are input simultaneously under the same railway communication system, and the designed system receives the signal to provide a solution for the further development of the communication industry.
