Compare advanced time-frequency analysis methods beyond STFT.

Advanced TF methods address STFT resolution limitations: Wavelet Transform (multi-resolution, better for transients), Wigner-Ville Distribution (fine resolution but cross-term interference for multi-component signals), Smoothed pseudo-Wigner (reduced cross-terms via smoothing), Cohen's class (generalized TF distributions), Chirplet transform (for chirp signals), Empirical Mode Decomposition (data-driven, no fixed basis), and Synchrosqueezing (sharpened TF representations). Selection criteria: Signal type (transients, chirps, multi-component), cross-term tolerance, computational complexity, and interpretability requirements. Often multiple methods provide complementary insights.
