Abstract. The article is devoted to the study of the possibility of estimating the frequency shift of the component components of the group signal with the combination of carrier frequencies using reference phase-shift keyed signals with a known synchrocombination structure. Analytical expressions are obtained for the additive mixture of subscriber signals with the combination of carrier frequencies, taking into account the Doppler frequency shift. The results of estimating the root-mean-square deviation of the error of the frequency shift of subscriber signals depending on the length of the sync pattern of the reference phase-shift keyed signal at different signal-to-noise ratios, obtained on the basis of simulation modeling, are presented. The results of the research can be used in solving the problems of geolocation of subscriber terminals of satellite communication systems operating on the technology of combining carrier frequencies.
Key words: satellite communication systems, carrier-in-carrier, frequency shift, sync combination, mutual uncertainty function.
