Abstract
In this paper, we study the problem of localizing wide-band sources in the presence of noise modeled as a complex isotropic stable process. We consider the frequency-domain representation of the sensor outputs and show that the spectral density of complex stable processes plays a role, in array processing problems, analogous to that played by the power spectral density of second-order processes.
