摘要： Provided are an apparatus and method for frame synchronization using phase differential information in a digital video broadcasting (DVB) transmission system. The apparatus includes a first correlator, a first comparator, and an acquisition controller. The first correlator calculates a first decision variable as correlation using phase differential information between a received symbol data sequence and start of frame (SOF) symbol sequences for frame synchronization in a SOF symbol duration. The first comparator compares the first decision variable with a predetermined first threshold value. The acquisition controller determines whether initial frame synchronization is archived or not according to the comparison result of the first comparison means and controlling the first correlation means to continuously operate until the initial frame synchronization is archived.
