摘要
本文指出几种常见的谱估计方法可以归结为同一数学问题并可用同一矩阵方程表示。从这通用矩阵表示可导出许多新的谱估计方法。本文还具体研究了相关阵特征矢量空间谱估计方法,得出一些有益的结论。
In this paper, it will be verified that many current spectral estimation methods are corresponding to a same mathematic problem. A common matrix form for spectral estimation methods will be given and a series of new approaches to spectral estimation can be extended from it. As an example, procedures based on the eigenvector space of the correlation matrix are investigated.
