Abstract
We consider the use of 2nd-and 4th-order cumulants for estimating the direction-of-arrival (DOAs) in narrow band array processing. The Fisher information about the DOAs contained in several cumulant statistics is computed. Numerical evaluation of the related Cram er-Rao bound is then used to point out, in this limited study, some advantages and drawbacks of using higher-order statistics.
