T. Dewson et al., ESTIMATING OF VOLTERRA KERNELS IN CASE OF MOMENT HIERARCHY AND ORTHOGONAL REPRESENTATION, Computers & mathematics with applications, 33(4), 1997, pp. 5-14
In this paper, two methods of the estimation of the kernels of a nonli
near model are considered. One is based on the orthogonalisation of th
e Gaussian input, the other one uses the moment hierarchy. Numerical e
xamples are added to demonstrate the usefulness of both methods.
