Research on non-stationary signal analyzer based on HHT;

Combined with comparatively perfect non-stationary signal analysis methods such as wavelet transform (WT) and Hilbert Huang transform (HHT), the blueprint of designing component-based non-stationary signal analyzer was put forward.

R&D on non-stationary signal analysis system based on parameter-sharing models

Blind separation of non-stationary signal based on non-orthogonal diagonalization algorithm;

On-line blind source separation of non-stationary signals by multiple time-delayed decorrelation rule;

To solve the difficulty of time-delay estimation for non-stationary signal,an improved estimation method based on short-time Fourier transform(STFT) spectrogram correlated with frequency domain is presented.

To analyze and deal with non-stationary signals, pe.

And this paper introduced the advantages of those methods in analyzing non-stationary signals and explains the merits and defects of those methods by analyzing the simulation signals.
