Example Embodiment
[0055] Next, the technical solutions in the embodiments of the present invention will be apparent from the embodiment of the present invention, and it is clearly described, and it is understood that the described embodiments are merely embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, there are all other embodiments obtained without making creative labor without making creative labor premises.
[0056]The receiver needs to determine the starting position of the frame by a reliable frame synchronization algorithm in the satellite channel environment. The physical layer frame head is an important basis for the receiver to implement frame synchronization and carrier recovery. Correct analysis of the frame header can obtain a frame length, modulation coding method, and whether there is information such as pilot. With common DVB-S2 (Digital Video Broadcasting-Satellite-Second Generation, Second Generation Satellite Digi...
