摘要

为了提升星地一体化通信用户接收终端钟差的同步校正准确度，提出基于正交频分复用（Orthogonal Frequency Division Multiplexing，OFDM）技术的星地一体化通信用户接收终端钟差同步校正方法。解析星地一体化通信过程中相对论效应产生的通信钟差干扰；根据校正的需求，求解接收信道的最优方向角，优化用户接收终端的接收信道；在此基础上，结合OFDM信号特点，根据通信信号的发射周期，将信号划分为不同的时间窗；建立同步校正的度量函数，估计OFDM信号的符号起始位置，通过预估误差补偿实现了对钟差的同步校正。经过实验测试可知，应用该方法进行OFDM信号校正处理后，通信信号波形更加规律；应用该方法进行钟差校正后钟差值较小，提升了星地一体化通信用户接收终端钟差同步校正的准确度。

Abstract

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.
