HOS-based direction of arrival estimation
A.R. Leyman, T.S. Durrani · Electronics Letters · 1994
A new technique for estimating the direction of arrival of multiple non-Gaussian signals using higher order statistics is reported. A set of new algorithms based on a new class of performance criteria related to the bispectral power of the array data is presented. Computer simulations show that the proposed algorithms outperform conventional array processing techniques.
