Abstract

In this paper we consider the problem of modeling 2-D system transfer functions given only bispectrum samples of the noisy output. This identification procedure is a three step process. First, the output bispectrum samples are calculated along a 2-D "slice" in the 4-D bispectrum frequency region. Next, these samples are used to obtain a rational model of the bispectrum slice via a 2-D divided difference approach. Finally, we develop two methods for finding the underlying system transfer function parameters bom this rational model. This system identification procedure is general in that it does not impose causality, recursibility, or minimum phase restrictions on the system to be identified.
