Abstract

In this contribution we discuss the translation-invariant interpolation of frequency domain functions by means of a well-conditioned Gaussian-modulated pole kernel which generates exclusively stable poles. For the implementation we use an adaptive interpolation process which is a variant of a recently introduced adaptive residual subsampling method. It is shown that the interpolation process with the Gaussian-modulated pole kernel also provides an excellent pre-processing interface when used in conjunction with the popular vector fitting algorithm. This results in a composite algorithm, performing the sampling and modelling of the given frequency function in a fully automatic way.

高斯调制极点核的良好条件自适应插值及其在矢量拟合中的应用

在这篇贡献中，我们讨论了利用一个产生完全稳定极点的条件良好的高斯调制极点核的频域函数的平移不变插值。对于实现，我们使用自适应插值过程，这是最近引入的自适应残差子抽样方法的变体。结果表明，高斯调制极点核插值过程与常用的向量拟合算法结合使用时，也提供了一个很好的预处理接口。这就产生了一种复合算法，以全自动的方式对给定的频率函数进行采样和建模。
