运用Volterra级数和离散傅立叶变换的理论推导了非线性系统的离散频域模型。
Accurate measurement of Volterra kernels is useful for modeling nonlinear devices and systems as well as for model validation. Applying Volterra series and discrete Fourier transform(DFT) theories to nonlinear system, the model of nonlinear system in discrete frequency-domain is proved in the paper. The basic multitone method to measure Volterra kernels in discrete frequency-domain is discussed in detail.
