Abstract (in Japanese) (See Japanese page) 
(in English) Time-frequency analysis is mainly used for analyzing acoustic signals. Short-time Fourier transform by Allen, et al. and continuous wavelet transform by Grossmann, et al. are representative methods for time-frequency analysis. On the other hand, synchrosqueezed wavelet transform by Daubechies, et al. improved frequency resolution by calculating angular frequency with continuous wavelet transform and its time derivative. In this paper, we propose an improving method by calculating angular frequency with time shift and describe its result.
