In the industry process,the signal of condition monitor system and fault diagnosis was corrupted by the noise from neighbor machines,which is influenced the accurately of state estimation and fault diagnosis for machine.The method was proposed that the noise and interference was extended as a source vector.The blind source separation(BSS) technique was employed.An algorithm was researched to removal interference and de-noise based on blind source separation,and is used in experiment of fault diagnosis for vibration signal of shaft.The result shown: the power spectrum that the signal of vibration was transacted is better than that of which isn't done with.The validity of BSS,in interference removal and de-noise,is verified by computer computing.
