| Abstract: | The blind source separation was used to recover the vibration signals of independent sources of aeroengine.The theory and separation of the aeroengine's vibration signals is expounded by using blind source separation techniques.It also carried out the separation of the vibration signals that come from rotor of a turbofan engine by Fast ICA algorithm. |
