Signal-Noise Separation Method Based on PSO for Vibration Signals
Hong Xia Pan, Jin Ying Huang · Advanced materials research · 2010
The wavelet analysis is combined with particle swarm optimization (PSO) which is applied to the de-noise process of vibration responding signals in this paper. The fault information has been enhanced. Furthermore, the signal-noise separation method based on particle swarm optimization for vibration signal and the diagnosis precision enhancement technology are studied, by means of the blind source separation technique.
