时频分析分类-信号时频分析理论

时频分析分类 (1) Short-time Fourier transform (STFT) (rec-STFT, Gabor, …) 平方 能量谱图 改进 S变换 (2) Wigner distribution function (WDF) 结合 Gabor-Wigner Transform 改进 加窗 WDF 改进 Cohen’s Class Distribution (Choi-Williams, Cone-Shape, …) 改进 Pseudo L-Wigner Distribution (4) Time-Variant Basis Expansion Matching Pursuit（匹配跟踪） 改进Chirplet变换 (5) Hilbert-Huang Transform (3) Wavelet transform Haar and Daubechies Coiflet, Morlet Directional Wavelet Transform (唯一逃脱Fourier transform 的架构) 非对称 STFT *
