This method first analyzes the characteristics of irrelevant signals between frames in the time domain in burst communication, and then uses higher-order cumulants to detect the start and end positions of each frame in the signal, and re-demodulates based on the detected positions to extract useful information and construct an analysis matrix. Then, based on the principle of frame synchronization code, rough estimation and precise estimation of the frame synchronization code are completed.
