Signal-subspace processing using higher orderstatistics
A.R. Leyman, T.S. Durrani · Electronics Letters · 1994
Eigendecomposition-based techniques such as MUSIC and its variants constitute effective methods for determining the direction of arrival (DOA) estimates of narrowband sources. A new strategy which extends the MUSIC algorithm to higher order statistics (HOS) is proposed for estimation of the DOA, and the number of multiple narrowband incoherent and coherent non-Gaussian signals. The performance of the technique is compared with other recently suggested HOS-based methods.
