| description | Understanding the influence of Doppler effect on the transmission performance of the Starlink system was an important prerequisite to decipher its unique physical layer structure.To this end, firstly a Doppler effect model considering relative motion between the satellites and the earth was established, and the maximum Doppler effect parameters of the Starlink was provided.Subsequently, a signal model under Doppler effect was constructed based on the Starlink downlink time-frequency structure and parameters.Finally, time-frequency domain theoretical characteristics under Doppler effect for the three main components of the downlink signal were established.The validity of the theoretical findings is corroborated through simulations, serving as a valuable reference for research on transmission reliability in existing and future low earth orbit satellite communication systems. |
