Minimum-latency Time-frequency Analysis Using Asymmetric Window Functions
Li Su, Hau-tieng Wu
We study the real-time dynamics retrieval from a time series via the time-frequency (TF) analysis with the minimal latency guarantee. While different from the well-known intrinsic…

Wave-shape function analysis -- when cepstrum meets time-frequency analysis
Chen-Yun Lin, Li Su, Hau-tieng Wu
We propose to combine cepstrum and nonlinear time-frequency (TF) analysis to study mutiple component oscillatory signals with time-varying frequency and amplitude and with time-var…
