| description | The invention belongs to the technical field of spectrum analyzer signal analysis, and particularly relates to a UW-based spectrum analyzer signal analysis synchronization method, which comprises the following steps: firstly, judging whether the length of a UW word of an input signal is an even number or an odd number, if the length is the even number, dividing the UW word into two parts with the same length N, otherwise, dividing the UW word into two parts with the same length N; after the last symbol of the UW word is discarded, the UW word is divided into a front part and a rear part which are the same in length N; calculating a modulation symbol rotation angle e (i); and finally, sliding rotation self-correlation is carried out to obtain a correlation coefficient, the size of each of the two sliding windows is N symbols, and the distance is also N symbols. Through the synchronization method based on sliding rotation autocorrelation, the frequency offset resistance characteristic in spectrum analyzer signa |
