Sampling Signals on Graphs: From Theory to Applications [PDF]
, 2020 The study of sampling signals on graphs, with the goal of building an analog of sampling for standard signals in the time and spatial domains, has attracted considerable attention recently. Beyond adding to the growing theory on graph signal processing (GSP), sampling on graphs has various promising applications.

Compressed Sampling in Shift-Invariant Spaces Associated With FrFT
IEEE Access, 2021 Shift-invariant and sampling spaces play a vital role in the fields of signal processing and image processing. In this paper, we extend the generalized shift-invariant and sampling subspaces from the traditional sampling spaces to the compressed sampling,

Orthogonal phase-frequency coded signal in a pulse against interrupted sampling repeater jamming
The Journal of Engineering, 2019 Interrupted sampling repeater jamming (ISRJ) uses the under sampling technology to transmit and repeat the radar intercepted signals. As a new kind of coherent interference, it is widely used in self-defence interference.

Intentional Aliasing Method to Improve Sub-Nyquist Sampling System [PDF]
Jehyuk Jang, Sanghun Im, and Heung-No Lee, "Intentional aliasing
method to improve sub-Nyquist sampling system," IEEE Transactions on Signal
Processing, pp. 3311-3326, Vol. 66, No. 12, Jun. 2018, 2017 A modulated wideband converter (MWC) has been introduced as a sub-Nyquist sampler that exploits a set of fast alternating pseudo random (PR) signals. Through parallel sampling branches, an MWC compresses a multiband spectrum by mixing it with PR signals in the time domain, and acquires its sub-Nyquist samples.

Estimating the Signal Reconstruction Error from Threshold-Based Sampling Without Knowing the Original Signal [PDF]
, 2018 The problem of estimating the accuracy of signal reconstruction from threshold-based sampling, by only taking the sampling output into account, is addressed. The approach is based on re-sampling the reconstructed signal and the application of a distance measure in the output space which satisfies the condition of quasi-isometry.

FEBS Letters, EarlyView.Metabolic dysfunction‐associated steatotic liver disease (MASLD) affects nearly one‐third of the global population and poses a significant risk of progression to cirrhosis or liver cancer. Here, we discuss the roles of hepatic dendritic cell subtypes in MASLD, highlighting their distinct contributions to disease initiation and progression, and their ...

Sampling of Correlated Bandlimited Continuous Signals by Joint Time-vertex Graph Fourier Transform [PDF]
arXiv, 2022 When sampling multiple signals, the correlation between the signals can be exploited to reduce the overall number of samples. In this paper, we study the sampling theory of multiple correlated signals, using correlation to sample them at the lowest sampling rate. Based on the correlation between signal sources, we model multiple continuous-time signals
