A wavelet domain spectral correlation method was proposed to detect MPSK signal overwhelmed in noise. Based on cyclic spectral correlation and affine time-frequency theory, wavelet spectral was expanded to wavelet spectral correlation domain and MPSK signal wavelet domain spectral correlation characteristic was analyzed. According to results of the analysis, steps of MPSK parameter estimation were proved. The simulation results show this method has good performance of detection in Low SNR.
Key words： MPSK signal; parameter estimation; wavelet spectral correlation
