离散阿贝尔群上的滤波器组

Filter Banks on Discrete Abelian Groups

Antonio Garcia Garcia, Miguel Angel Hernandez-Medina, Gerardo Perez-Villalon

摘要:

在这项工作中,我们提供了多相,调制和帧理论分析的滤波器组上的离散阿贝尔群。因此,多维或循环滤波器组以及$\ell^2(\mathbb{Z}^d\times \mathbb{Z}_s)$或$\ell^2(\mathbb{Z}_r \times \mathbb{Z}_s)$空间中的信号的滤波器组以统一的方式被研究。我们得到了完美重构的条件和相应的框架界。

英文摘要:

In this work we provide polyphase, modulation, and frame theoretical analyses of a filter bank on a discrete abelian group. Thus, multidimensional or cyclic filter banks as well as filter banks for signals in $\ell^2(\mathbb{Z}^d\times \mathbb{Z}_s)$ or $\ell^2(\mathbb{Z}_r \times \mathbb{Z}_s)$ spaces are studied in a unified way. We obtain perfect reconstruction conditions and the corresponding frame bounds.
