Ensemble empirical mode decomposition method (EEMD) is important improvement of the empirical mode decomposition (EMD), but it still leaves some annoying difficulties unresolved, such as large computational cost and reconstruction error. To solve above problems of the EEMD, a new method named EEMD of adaptive noise (EEMDAN) is proposed, which can ...

Reconstruction and Evaluation of Ship Radiated Noise Signal in Ocean Channel
2020 4th Annual International Conference on Data Science and Business Analytics (ICDSBA), 2020Ship radiated noise can generally be regarded as a random process that undergoes steady states, but the complexity of its generation mechanism makes its spectral characteristics different from white noise signals. Realistic simulation of the time domain signal of ship radiated noise can improve performance of acoustic equipment.

Neural Network Approach for Automatic Classification of Ship-Radiated Noise
Japanese Journal of Applied Physics, 2006Tonal signals from ship-radiated noise contain important information for a ship's design, maintenance, operating condition diagnosis, and machinery monitoring. The signals mainly consist of two components–the speed-dependent component and the speed-independent component.
