GSM multi-slot signal synchronization method based on TSC sequence phase difference

The invention discloses a GSM multi-slot signal synchronization method based on TSC sequence phase difference, and belongs to the technical field of information. According to the invention, an original signal is converted to an expected sampling rate; carrying out matched filtering on the signals after variable sampling, and filtering interference noise; generating an ideal TSC sequence signal, and performing segmentation correlation operation on the ideal TSC sequence signal and the filtered signal; respectively calculating a phase difference accumulated value of adjacent signals in each section; and finding out a minimum phase difference accumulated value, and obtaining a synchronization point of the GSM multi-slot signal. According to the method, the TSC sequence phase difference is used for searching the synchronization point of the GSM multi-slot signal, the overall calculation complexity is low, and the measurement speed is increased while the measurement precision is met. 本发明公开了一种基于TSC序列相位差的GSM多时隙信号同步方
