Abstract
A bispectral application is developed by considering a fully two-dimensional region of support in the cumulant domain. An asymptotically Hermitian block-Toeplitz matrix composed of third-order cumulants is built. Using a noise subspace-based frequency estimator, a two-dimensional frequency kernel is projected on the orthogonal complement subspace. The reciprocal of this projection is the frequency estimator indicating the location of a triple of phase-coupled sinusoids in the bispectral domain. The method provides accurate, high-order spectrum estimation. In general, transfer function parameterization is implicated in higher-order spectral estimation when one-dimensional or diagonal slices are used.
