Abstract
Mainly adopting adaptive filtering algorithm which is based on EMD-LMS, this paper made spectral analysis of the filtered signal by simulation experiment and then compared it with the classical spectral analysis method and wavelet de-noising method. It verified the validity and superiority of the spectral analysis method based on EMD-LMS. The experimental results show that the method adopted in this paper has better resolution to spectrum analysis of Ship radiated noise simulation signal. By using adaptive filtering techniques combined by EMD and least mean square (LMS), make a spectrum analysis of period gram method and autocorrelation method to filtered signal. Compared it with the classical spectral analysis method and wavelet de-noising method, and then we get the spectrum analysis of ship radiated noise simulation signal based on EMD-LMS.
