Second-order blind source separation based on multi-dimensional autocovariances

Theis, Fabian J. ; Meyer-Bäse, A. ; Lang, Elmar


SOBI is a blind source separation algorithm based on time decorrelation. It uses multiple time autocovariance matrices, and performs joint diagonalization thus being more robust than previous time decorrelation algorithms such as AMUSE. We propose an extensioncalled mdSOBI by using multidimensional autocovariances, which can be calculated for data sets with multidimensional parameterizations ...
