  author={DelftThe Netherlandsypma and HelsinkiFinlandPetteri. Pajunen},
We present a novel approach to signal separation using temporal correlations, which may be useful in decomposition of multichannel vibration data into fault-related harmonic activity. Performance of the algorithm with respect to parameter settings is investigated with artiicial data, whereas vibration data from a submsersible pump is used to compare the second-order ICA algorithm to other methods for ICA and feature extraction in machine vibration.
