Features of Frequency Synchronization Algorithms DVB-S2(X) for LEO Satellites

The article is devoted to studying the features of the application of the frequency synchronization algorithms in the second generation satellite broadcasting standard DVB-S2X for LEO satellites. In the course of the work, we calculated the Doppler shift values for a low-orbit satellite in the Ka-band, estimated minimum symbol rate, showed that the conventional set of algorithms could work with small changes, simulated frequency synchronization, and found the optimal parameters of the algorithms for normal and VLSNR frames.
