Abstract

When the spacecraft is moving at high speed, the signal obtained by the control station always exists Doppler shift, which is reflected in the DQPSK signal. In order to make the digital signal demodulate the correct information, this paper analyzes the influence of Doppler on demodulation, and studies the modified Doppler method based on DSTFT to ensure that Doppler interference does not interfere with the normal demodulation.
