On uncertainty principle for quaternionic linear canonical transform

KI Kou, JY Ou, J Morais - Abstract and Applied Analysis, 2013 - Wiley Online Library
We generalize the linear canonical transform (LCT) to quaternion‐valued signals, known as
the quaternionic linear canonical transform (QLCT). Using the properties of the LCT we …

Octonion spectrum of 3D short-time LCT signals

Unified Wigner–Ville distribution and ambiguity function in the linear canonical transform domain

ZC Zhang - Signal Processing, 2015 - Elsevier
In this paper, we propose a novel integral transform by combining the generalized Wigner–
Ville distribution (WDL) with the linear canonical transform (LCT). The new integral transform …

Uncertainty principles for hypercomplex signals in the linear canonical transform domains

Y Yang, KI Kou - Signal Processing, 2014 - Elsevier
Linear canonical transforms (LCTs) are a family of integral transforms with wide application
in optical, acoustical, electromagnetic, and other wave propagation problems. The Fourier …

Quaternion windowed linear canonical transform of two-dimensional signals

WB Gao, BZ Li - Advances in Applied Clifford Algebras, 2020 - Springer
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 …

Some properties of windowed linear canonical transform and its logarithmic uncertainty principle

M Bahri, R Ashino - International Journal of Wavelets …, 2016 - World Scientific
Based on the relationship between the Fourier transform (FT) and linear canonical transform
(LCT), a logarithmic uncertainty principle and Hausdorff–Young inequality in the LCT …

Uncertainty principles for the short-time linear canonical transform of complex signals

WB Gao, BZ Li - Digital Signal Processing, 2021 - Elsevier
The short-time linear canonical transform (STLCT) is a novel time-frequency analysis tool. In
this paper, we generalize some different uncertainty principles for the STLCT of complex …

Uncertainty principle for the two-sided quaternion windowed linear canonical transform

WB Gao, BZ Li - Circuits, Systems, and Signal Processing, 2022 - Springer
In this paper, we investigate the (two-sided) quaternion windowed linear canonical transform
