摘要：
A new method of estimating the Volterra kernels in the frequency-domain is introduced based on a non-parametric algorithm. Unlike the traditional non-parametric methods using the frequency-domain formulations based on discrete Fourier transform (DFT) data, this new approach uses the time-domain measurements directly to estimate the frequency-domain response functions.
