Discrete Linear Canonical Transform on Graphs
Yu Zhang, Bing-Zhao Li
With the wide application of spectral and algebraic theory in discrete signal processing techniques in the field of graph signal processing, an increasing number of signal processi…
Spectral graph fractional Fourier transform for directed graphs and its application
Fang-Jia Yan, Bing-Zhao Li
In graph signal processing, many studies assume that the underlying network is undirected. Although the digraph model is rarely adopted, it is more appropriate for many application…
Multi-dimensional graph fractional Fourier transform and its application
Fang-Jia Yan, Bing-Zhao Li
Many multi-dimensional signals appear in the real world, such as digital images and data that has spatial and temporal dimensions. How to show the spectrum of these multi-dimension…
Uncertainty principle for the two-sided quaternion windowed linear canonical transform
Wen-Biao Gao, Bing-Zhao Li
In this paper, we investigate the (two-sided) quaternion windowed linear canonical transform (QWLCT) and study the uncertainty principles associated with the QWLCT. Firstly, severa…
Uncertainty principles for the windowed Hankel transform
Wen-Biao Gao, Bing-Zhao Li
The aim of this paper is to prove some new uncertainty principles for the windowed Hankel transform. They include uncertainty principle for orthonormal sequence, local uncertainty…
Uncertainty principles for the short-time linear canonical transform of complex signals
Wen-Biao Gao, Bing-Zhao Li
The short-time linear canonical transform (STLCT) can be identified as a generalization of the short-time Fourier transform (STFT). It is a novel time-frequency analysis tool. In t…
Uncertainty principles for the windowed offset linear canonical transform
Wen-Biao Gao, Bing-Zhao Li
The windowed offset linear canonical transform (WOLCT) can be identified as a generalization of the windowed linear canonical transform (WLCT). In this paper, we generalize several…
Quaternion Windowed Linear Canonical Transform of Two-Dimensional Quaternionic Signals
Wen-Biao Gao, Bing-Zhao Li
We investigate the 2D quaternion windowed linear canonical transform(QWLCT) in this paper. Firstly, we propose the new definition of the QWLCT, and then several important propertie…
