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

Graph Signal Processing: Overview, Challenges, and Applications [PDF]

open access: yesProceedings of the IEEE, 2017
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, along

Topological Signal Processing Over Simplicial Complexes [PDF]

open access: yesIEEE Transactions on Signal Processing, 2019
The goal of this paper is to establish the fundamental tools to analyze signals defined over a topological space, i.e. a set of points along with a set of neighborhood relations.

Nonuniform sampling and reconstruction of Diracs signal associated with linear canonical transform and its application

open access: yesEURASIP Journal on Advances in Signal Processing, 2023
Sampling and reconstruction play a critical role in signal processing. The non-ideal sampling conditions motivate the development of the sampling theory. In this paper, associated with multiple non-ideal conditions, we discuss the nonuniform sampling and

Introducing Hypergraph Signal Processing: Theoretical Foundation and Practical Applications [PDF]

open access: yesIEEE Internet of Things Journal, 2019
Signal processing over graphs has recently attracted significant attention for dealing with the structured data. Normal graphs, however, only model pairwise relationships between nodes and are not effective in representing and capturing some high-order ...

Period and Signal Reconstruction from the Curve of Sample-Sequences [PDF]

open access: yesIET Signal Process. 16 (2), 2022, pp. 232-237, 2020
A finite sequence of equidistant samples (a sample train) of a periodic signal can be identified with a point in a multi-dimensional space. Such a point depends on the sampled signal, the sampling period, and the starting time of the sequence. If the starting time varies, then the corresponding point moves along a closed curve.

Influence of Analog-To-Digital Conversion and Decimation Parameters on the Signal-To-Noise Ratio in the Radar Path

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника, 2021
Introduction. The digital representation of received radar signals has provided a wide range of opportunities for their processing. However, the used hardware and software impose some limits on the number of bits and sampling rate of the signal at all ...
