BLIND SEPARATION OF CONVOLUTIVE MIXTURES A CONTRAST-BASED JOINT DIAGONALIZATION APPROACH
Pierre Comon, Ludwig Rota · 2001
Blind Separation of convolutive mixtures and Blind Equalization of Multiple-Input Multiple-Output (MIMO) channels are two different ways of naming the same problem, which we address here. The numerical algorithm, subsequently presented in detail, is based on theoretical results on contrasts recently published by the authors [1]. This algorithm consists of Partial Approximate Joint Diagonalization (PAJOD) of several matrices, containing some values of output cumulant multi-correlations.
