Description
Summary:This paper introduces a blind MIMO equalization algorithm for convolutive mixtures. A parametrization of the equalizer is proposed when observations are whitened. From theoretical results, a numerical algorithm is then derived. This algorithm is based on the solution of a polynomial system, which some values of output cumulant multi-correlations enter. Simulations and performance of the numerical algorithm are also included.
