| description | In order to improve the accuracy of clock synchronization correction for the receiving terminal of integrated satellite ground communication users, a clock synchronization correction method for the receiving terminal of integrated satellite ground communication users based on Orthogonal Frequency Division Multiplexing (OFDM) technology was proposed. Analyzed the communication clock bias interference caused by relativistic effects in the process of integrated satellite ground communication. According to the calibration requirements, solved the optimal direction angle of the receiving channel and optimized the receiving channel of the user's receiving terminal. Based on this, combined with the characteristics of OFDM signals, the signal was divided into different time windows according to the transmission period of the communication signal. Established a measurement function for synchronous correction, estimated the symbol starting position of OFDM signals, and achieved synchronous correction of clock bias through error compensation estimation. After experimental testing, it was found that applying this method for OFDM signal correction processing resulted in a more regular waveform of the communication signal. After applied this method for clock bias correction, the clock bias was relatively small, which improved the accuracy of clock bias synchronization correction for satellite ground integrated communication user receiving terminals. |
