DOA estimation via higher-order cumulants: a generalized approach

Abstract

A general relation between the cumulant functions and the direction of arrival (DOA) parameters is developed. Using this relation it is shown that several DOA estimation algorithms can be obtained. One of these algorithms, involving the use of a Hankel matrix, is developed and its performance is studied in computer simulations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
