Physical layer synchronization algorithms for signal-code sequence increasing noise immunity of dvb-s2x standard vl-snr mode

Abstract

The work is devoted to expanding the noise immunity of the DVB-S2X standard and the VL-SNR mode physical layer synchronization algorithms. The article proposes a signal-code sequence that increases the noise immunity of the signal, operating down to −11 dB signal-to-noise ratio, and a synchronization system for it.
