Abstract :
In this paper, a robust and reliable frame synchronization method is developed for satellite-based DVB-S2 system. To perform frame synchronization accurately and rapidly under the condition of low signal-to-noise ratios and large carrier frequency offset, a novel frame synchronization scheme combining pilot-symbol-assisted differential correlation with double-peak search algorithm is analytically investigated and evaluated by extensive simulations. Simulation results show that the proposed method can achieve much lower false synchronization probability in comparison with the existing ones with low complexity overhead. Furthermore, time to acquire frame synchronization is reduced to a desirable level, even under much worse channel condition than specified.
