本文讨论频率域测量非线性系统Volterra核的快速准确算法。应用Volterra泛函级数和离散傅里叶变换理论于非线性系统
本文给出非线性系统在离散频率域的模型。应用该模型并适当地选取输入正弦信号的频率
可以同时多点地测量非线性系统的前三阶核。
The fast and efficient QMMP algorithm of measuring first three Volterra kernels in nonlinear system is presented in this paper. Applying Volterra functional series and discrete Fourior tansform (DFT) to the system
we can obtain the model of the system in discrete frequency domain. Using this model and carefully choosing the frequencies of input sinusoidal signal
the first three Volterra kernels can be measured with many points.
