Abstract: A satellite broadcasting frame signal demodulation method is disclosed. A demodulation method of a demodulator that demodulates a Digital Video Broadcasting-Satellite—Second Generation (DVB-S2) standard satellite broadcasting frame signal includes: performing symbol synchronization; performing frame synchronization after symbol synchronization; recovering a carrier wave after frame synchronization; and decoding mode code (MODCOD) information to obtain frame configuration information after recovering the carrier wave. This method ensures rapid demodulation and reliable demodulated data.
