Convolution theorems for the free metaplectic transformation and its application
Hui Zhao, Bing-Zhao Li
The free metaplectic transformation (FMT) is widely used in many fields such as filter design, pattern recognition, image processing and optics. In order to obtain a more concise a…
Sampling theorems associated with offset linear canonical transform by polar coordinates
Hui Zhao, Bing-Zhao Li
The sampling theorem for the offset linear canonical transform (OLCT) of bandlimited functions in polar coordinates is an important signal analysis tool in many fields of signal pr…
The two-dimensional OLCT of angularly periodic functions in polar coordinates
Hui Zhao, Bing-Zhao Li
The two-dimensional (2D) offset linear canonical transform (OLCT) in polar coordinates plays an important role in many fields of optics and signal processing. This paper studies th…
Unlimited Sampling Theorem Based on Fractional Fourier Transform
Hui Zhao, Bing-Zhao Li
The recovery of bandlimited signals with high dynamic range is a hot issue in sampling research. The unlimited sampling theory expands the recordable range of traditional analog-to…
