摘要

本文提出了一种新的临界采样Gabor变换。这个变换，不像目前所有可用的临界采样Gabor变换，导致一个稳定的变换。此外，得到的双正交函数在临界采样情况下是唯一的，在时间和频率上都有很好的局部化。这样就克服了以前变换的两个主要问题。

Stable critically-sampled Gabor transform with localized biorthogonal function

In this paper, a new critically-sampled Gabor transform is presented. This transform, unlike all currently available critically-sampled Gabor transforms, leads to a stable transform. In addition, the resulting biorthogonal function, which is unique in the critical sampling case, is well localized in both time and frequency. It thus overcomes the main two problems of previous transforms.
