JOINT APPROXIMATE DIAGONALIZATIONS AND APPLICATION TO VIRTUAL ARRAYS
Laurent Albera · 2003
The problem of Blind Identification of linear mixtures of independent random processes is often related to the diagonalization of some tensors. This problem is posed here in terms of a non conventional joint approximate diagonalization of several matrices. In fact, a single congruent transform is applied to each of these matrix; the left transform being rectangular full rank, and the right one being unitary. The application in antenna signal processing is described, and suboptimal numerical algorithms are proposed.
