specific Embodiment approach
[0077] refer to figure 2 , the embodiment of the present invention provides a method for timing synchronization of burst signals in satellite communications, the method is implemented by a timing synchronization module in a receiver (i.e. receiving terminal), specifically comprising:
[0078] 101. Perform sliding window calculation on the received burst signal, and obtain the position of the maximum value in the calculation result.
[0079] Specifically, for a TDMA burst communication system, some communication methods (such as GMR-1) have bursts with very short unique words (such as NT3 bursts) and even bursts without unique words (such as NT3 bursts) in their burst types (such as GMR-1). DKAB burst).
[0080] In this embodiment, this step is realized by the most value acquisition unit 11. For the burst structure with unique words, the most value acquisition unit 11 uses a sliding window to compare the unique word corresponding to the received burst signal with the unique w...
