2017. Polyharmonic test signals application for identification of nonlinear dynamical systems based on volterra model. 2017 International Conference on Information and Telecommunication Technologies and Radio Electronics (UkrMiCo). :1–5.
The new criterion for selecting the frequencies of the test polyharmonic signals is developed. It allows uniquely filtering the values of multidimensional transfer functions - Fourier-images of Volterra kernel from the partial component of the response of a nonlinear system. It is shown that this criterion significantly weakens the known limitations on the choice of frequencies and, as a result, reduces the number of interpolations during the restoration of the transfer function, and, the more significant, the higher the order of estimated transfer function.
