Graph Signal Processing: Overview, Challenges and Applications

open access: yesProceedings of the IEEE, 2018
Research in Graph Signal Processing (GSP) aims to develop tools for processing data defined on irregular graph domains. In this paper we first provide an overview of core ideas in GSP and their connection to conventional digital signal processing.

Pulse-doppler signal processing with quadrature compressive sampling [PDF]

open access: yesIEEE Transactions on Aerospace and Electronic Systems, 2015
Quadrature compressive sampling (QuadCS) is a recently introduced sub-Nyquist sampling scheme for effective acquisition of inphase and quadrature (I/Q) components of sparse radio frequency signals. In applications to pulse-Doppler radars, the QuadCS outputs can be arranged into a two-dimensional data format, in terms of slow time and virtual fast time,

Design of a Digital Array Signal Processing System with Full Array Element

open access: yesRemote Sensing, 2023
For the application of a digital array signal processing system with a high sampling rate and large bandwidth, and considering the constraints of limited resources (performance, volume, power consumption, weight, etc.), this paper proposes a design and ...

Highlighting Problems Occurring in Analysis of Critical Sampling of Cosinusoidal Signal [PDF]

open access: yesTransNav, 2020
When the sampling of an analog signal uses the sampling rate equal to exactly twice the value of a maximal frequency occurring in the signal spectrum, it is called a critical one.

Coprime sampling for nonstationary signal in radar signal processing [PDF]

open access: yesEURASIP Journal on Wireless Communications and Networking, 2013
Estimating the spectrogram of non-stationary signal relates to many important applications in radar signal processing. In recent years, coprime sampling and array attract attention for their potential of sparse sensing with derivative to estimate autocorrelation coefficients with all lags, which could in turn calculate the power spectrum density.

Event-Based Sensing and Signal Processing in the Visual, Auditory, and Olfactory Domain: A Review

open access: yesFrontiers in Neural Circuits, 2021
The nervous systems converts the physical quantities sensed by its primary receptors into trains of events that are then processed in the brain. The unmatched efficiency in information processing has long inspired engineers to seek brain-like approaches ...

Adaptive importance sampling in signal processing [PDF]

open access: yesDigital Signal Processing, 2015
In Bayesian signal processing, all the information about the unknowns of interest is contained in their posterior distributions. The unknowns can be parameters of a model, or a model and its parameters. In many important problems, these distributions are impossible to obtain in analytical form.

Real-Time Eye Diagram Monitoring for Optical Signals Based on Optical Sampling

open access: yesApplied Sciences, 2023
A real-time eye diagram monitoring method for optical signals is proposed and experimentally demonstrated based on optical sampling. In the system, the optical signals under test are directly sampled by an optical sampling pulse train with a narrow pulse
