Robust Preprocessing: Denoising and Whitening in the context of Blind Source Separation of Instantaneous Mixtures

In this paper the feasibility and performance of two different preprocessing schemes for blind source separation (BSS) problems have been investigated. BSS is a promising technique for non-destructive machine condition monitoring by vibration and acoustic analysis. BSS methods offer non-invasive and inexpensive solution by restoring the specific signature… CONTINUE READING
