Convolution Type of Metaplectic Cohen's Distribution Time-Frequency Analysis Theory, Method and Technology
Manjun Cui, Zhichao Zhang, Jie Han +2
The conventional Cohen's distribution can't meet the requirement of additive noises jamming signals high-performance denoising under the condition of low signal-to-noise ratio, it…
Least-Squares Adaptive Filter-Based Cohen's Class Time-Frequency Distribution for Signal Denoising
Manjun Cui, Zhichao Zhang, Yangfan He
Inspired by the use of adaptive kernel-based Cohen's class time-frequency distributions (CCTFDs) for cross-term suppression, this paper aims to explore novel adaptive kernel functi…
Multi-dimensional Graph Linear Canonical Transform
Na Li, Zhichao Zhang, Jie Han +2
Many multi-dimensional (M-D) graph signals appear in the real world, such as digital images, sensor network measurements and temperature records from weather observation stations.…
Graph Linear Canonical Transform Based on CM-CC-CM Decomposition
Na Li, Zhichao Zhang, Jie Han +2
The graph linear canonical transform (GLCT) is presented as an extension of the graph Fourier transform (GFT) and the graph fractional Fourier transform (GFrFT), offering more flex…
