Signal Processing Based on Wavelet and Phase Space Reconstruction
HE Jin-lai · Mechanical Science and Technology · 2000
For time signal, the wavelet transform is equivalent to a kind of phase space reconstruction. Through wavelet transform, the signal can be decomposed and projected on H-G plane of reconstructed phase space. In H-G plane, the faint characteristic can be observed obviously. In simulation, periodical, quasi-periodical, chaotic signal is processed, the result is satisfactory.
