摘要

本文研究了频率同步算法在低轨道卫星第二代卫星广播标准DVB-S2X中的应用特点。在工作过程中，我们计算了一颗低轨道卫星在ka波段的多普勒频移值，估计了最小符号率，表明了常规算法可以在很小的变化下工作，模拟了频率同步，并找到了正常帧和超大信噪比帧下算法的最优参数。

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.
