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.

Алгоритмы синхронизации физического уровня для сигнально-кодовой конструкции, повышающей помехоустойчивость режима vl-snr стандарта dvb-s2x

Работа посвящена повышению помехоустойчивости сигнала стандарта DVB-S2X и алгоритмам синхронизации физического уровня режима VL-SNR. В статье предложена сигнально-кодовая конструкция, увеличивающая помехоустойчивость сигнала и работающая при отношении сигнал/шум (SNR) до -11 дБ, а также система синхронизации к ней.
