Orthogonal phase-frequency coded signal in a pulse against interrupted sampling repeater jamming

open access: yesThe 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.

Simple Proof of Incorrectness of the Formula Describing Aliasing and Folding Effects in Spectrum of Sampled Signal in Case of Ideal Signal Sampling [PDF]

open access: yesTransNav, 2021
A simple proof of the incorrectness of the formula, which is used in the literature nowadays, for description of the aliasing and folding effects in the spectrum of a sampled signal in the case of an ideal signal sampling, is given in this paper.

Generalised discretisation of continuous-time distributions

open access: yesThe Journal of Engineering, 2020
In this study, the definition of discretisation that was proposed recently for continuous-time distributions is made applicable not only to ordinary functions but to a variety of distributions including weak derivatives such that they could be viewed ...

Achieving Robust Compressive Sensing Seismic Acquisition with a Two-Step Sampling Approach

open access: yesSensors, 2023
The compressive sensing (CS) framework offers a cost-effective alternative to dense alias-free sampling. Designing seismic layouts based on the CS technique imposes the use of specific sampling patterns in addition to the logistical and geophysical ...

Sampling and Reconstruction of Spatial Fields using Mobile Sensors [PDF]

open access: yes, 2012
Spatial sampling is traditionally studied in a static setting where static sensors scattered around space take measurements of the spatial field at their locations.

An Investigation on the Sampling Frequency of the Upper-Limb Force Myographic Signals

open access: yesSensors, 2019
Force myography (FMG) is an emerging method to register muscle activity of a limb using force sensors for human−machine interface and movement monitoring applications.

A hardware prototype of wideband high‐dynamic range analog‐to‐digital converter

open access: yesIET Circuits, Devices and Systems, 2023
Key parameters of analog‐to‐digital converters (ADCs) are their sampling rate and dynamic range. Power consumption and cost of an ADC are directly proportional to the sampling rate; hence, it is desirable to keep it as low as possible.

Send-On-Delta Concept: An Event-Based Data Reporting Strategy

open access: yesSensors, 2006
The paper addresses the issue of the send-on-delta data collecting strategy tocapture information from the environment. Send-on-delta concept is the signal-dependenttemporal sampling scheme, where the sampling is triggered if the signal deviates by ...

An Optimal Dimensionality Sampling Scheme on the Sphere for Antipodal Signals In Diffusion Magnetic Resonance Imaging

open access: yes, 2015
We propose a sampling scheme on the sphere and develop a corresponding spherical harmonic transform (SHT) for the accurate reconstruction of the diffusion signal in diffusion magnetic resonance imaging (dMRI).
