Embodiment 1
[0064] In Embodiment 1, a burst signal frequency offset correction method applied to satellite phones is provided, please refer to Figure 1-Figure 5 , the method includes:
[0065] S10, receiving a signal and performing data buffering;
[0066] S20, generating a local standard sequence and performing shaping filtering processing;
[0067] S30, performing sliding correlation on the buffered signal and the sequence after local shaping and filtering, and finding the starting position of the burst signal according to the correlation peak;
[0068] S40, according to the obtained start position of the burst signal, take out a complete set of burst signal and the local standard sequence from the buffer to calculate the phase difference of the corresponding point;
[0069] S50, obtain the phase difference slope according to the N corresponding points received continuously, wherein the N is a positive integer greater than or equal to 2;
[0070] S60, performing dephase jump and deb...
