    Abstract: Provided is a frame synchronization method for synchronizing frames with pilot blocks added thereto based on differential correlation information in a satellite communication system. The method can acquire a highly reliable frame synchronization estimation value by achieving a multi-step threshold value test using pilot blocks after a correlation analysis and a threshold test based on a sync signal in order to resolve the problem of a low signal-to-noise ratio and a large frequency error and acquire highly reliable frame synchronization performance, and can overcome distortion of a correlation analysis value caused by the frequency error by analyzing correlation based on differential information. The method includes the steps of: a) performing correlation analysis and a threshold test by using a sync word; and b) performing a multi-step correlation value test by using the pilot blocks added to the frames prior to the sync word.
