描述了为单端口无源数字系统构建无损逆散射(LIS)问题的合理解决方案的方法。第一种方法是递归的,可以看作是著名的 Schur 算法的推广。第二种方法是全局的,导致我们所谓的基本解决方案的参数化,所有 LIS 解决方案都可以从中构建。估计理论和网络理论中的不少经典问题都可以看作是LIS问题的特例。对于每个基本解决方案,都有相应的估计问题的解决方案,从而导致给定随机过程的预测和建模过滤器。
Methods to construct rational solutions of the lossless inverse scattering (LIS) problem for one-port passive digital systems are described. The first method is recursive and can be viewed as a generalization of the celebrated Schur algorithm. The second method is global and leads to a parametrization of what we call fundamental solutions from which all LIS solutions may be constructed. Quite a few classical problems in estimation theory and network theory may be viewed as special cases of the LIS problem. With each fundamental solution there is a solution of a corresponding estimation problem leading to a prediction and a modeling filter for a given stochastic process.
