Abstract

The basic theory of frames is reviewed, and special topics dealing with Gabor frames and decompositions are developed. These topics include Gabor decompositions of L1 and of Bessel potential spaces. (Sobolev spaces are Bessel potential spaces.) Frames of translates in L2 are characterized; and the Balian–Low theorem for L2 is proved. The former result is not only useful for the Gabor theory, but is the basis of multiresolution analysis frames; the latter result is related to the classical uncertainty principle inequality.

L2和相关空间的Gabor框架

回顾了框架的基本理论，并对Gabor框架及其分解进行了专题讨论。这些主题包括L1和贝塞尔势空间的Gabor分解。(索博列夫空间是贝塞尔势空间。)第二语言翻译的框架具有特征;并证明了L2的Balian-Low定理。前者的结果不仅对Gabor理论有用，而且是多分辨率分析框架的基础;后一个结果与经典测不准原理不等式有关。
