Time-Frequency Analysis of Noisy Vibration Signal Based on Improved Hilbert-Huang Transform

Time-Frequency Analysis of Noisy Vibration Signal Based on Improved Hilbert-Huang Transform

Aimed at the phenomenon of modal confusion and lack of practical significance of instantaneous frequency caused by Hilbert-Huang transform (HHT) noisy vibration signal time-frequency analysis, complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) is obtained by improving empir...
