New ideas for Higher-Order Array Processing are introduced. The paper focuses on fourth-order cumulant statistics. They areexpressedin an index-freeformalism(that is believedto beof generalinterest ) allowing theexploitation of all their symmetry properties. We show that, when dealing with 4-index quantities, symmetries are related to rank properties.Therich symmetrystructureyieldsa wholeclassof newidentification algorithms.Main featuresare: • Use of fourth-order cumulant statistics only… CONTINUE READING
