Blind system identification in an impulsive environment

Abstract

A method is presented for blind system identification in an impulsive environment, where the system output is described by a symmetric /spl alpha/-stable (S/spl alpha/S) law. The method employs either the phase or the magnitude of the recently proposed /spl alpha/-spectrum of the system output. It is much simpler than the method proposed previously which also relies on the phase or magnitude of the /spl alpha/-spectrum, and provides the system cepstrum via closed form expressions.
