摘要
Signals commonly found in real-world applications are non-linear, multi-component, and non-stationary. For simplicity, they are analyzed and processed in time-frequency (TF) domain. Wigner-Ville distribution (WVD) is a method that provides time-frequency representation (TFR) of a signal with high-sharpness resolutions. However, its bilinear nature causes false frequency components called “cross-te...
