摘要
Abstract
Based on the FM modulation mode of the system, by calculating and analyzing Doppler frequency change rules, using intermediate frequency simulation experiment, it is proved that since low end spectrum is far higher than disturbance modulation frequency, the Doppler effect has no effect on the data transmission of high-speed train-ground communication system.关键词
