BLIND SOURCE SEPARATION: A PARTIAL JOINT DIAGONALIZATION (PAJOD) APPROACH

Blind Separation of convolutive mixtures and Blind Equaliza- tion of Multiple-Input Multiple-Output (MIMO) channels are two different ways of naming the same problem, which we address here. A novel MIMO optimization criterion, subse- quently presented in this paper, consists of a Partial Approxi- mate Joint Diagonalization (PAJOD) of several matrices, con- taining some values of output cumulant multi-correlations. A numerical algorithm is then devised, which works block-wise, and sweeps all the output pairs.
