Discrete Linear Canonical Transform on Graphs
In this paper, we propose and design the definition of the discrete linear canonical transform on graphs (GLCT), which is an extension of the discrete linear canonical transform (DLCT), just as the graph Fourier transform (GFT) is an extension of the discrete Fourier transform (DFT).
The two-dimensional OLCT of angularly periodic functions in polar coordinates
The two-dimensional (2D) offset linear canonical transform (OLCT) in polar coordinates plays an important role in many fields of optics and signal processing.
Unlimited Sampling Theorem Based on Fractional Fourier Transform
The recovery of bandlimited signals with high dynamic range is a hot issue in sampling research.
Multi-dimensional graph fractional Fourier transform and its application
Many multi-dimensional signals appear in the real world, such as digital images and data that has spatial and temporal dimensions.
