Égalisation aveugle de mélanges convolutifs MIMO

This article describe a novel algorithm for blind equalization of convolutives mixtures in a multipath environment. The equalizer is factorized with plane rotations and pure delays. The best equalizer is searched by testing roots of a polynomial system based on values of observed cumulants. Contrary to PAJOD [3] [2], the para-unitary matrix is not made of semi-unitary matrices, but with an exact factorization.
