Near-Optimal Graph Signal Sampling by Pareto Optimization [PDF]
Sensors, 2021 In this paper, we focus on the bandlimited graph signal sampling problem. To sample graph signals, we need to find small-sized subset of nodes with the minimal optimal reconstruction error.

Consistent Sampling and Signal Recovery [PDF]
IEEE Transactions on Signal Processing, 2007 An attractive formulation of the sampling problem is based on the principle of a consistent signal reconstruction. The requirement is that the reconstructed signal is indistinguishable from the input in the sense that it yields the exact same measurements. Such a system can be interpreted as an oblique projection onto a given reconstruction space.

Definition of Sampled Signal Spectrum and Shannon’s Proof of Reconstruction Formula [PDF]
TransNav, 2022 The objective of this paper is to show from another perspective that the definition of the spectrum of a sampled signal, which is used at present by researchers and engineers, is nothing else than an arbitrary choice for what is possibly not uniquely ...

Period and signal reconstruction from the curve of trains of samples
IET Signal Processing, 2022 A finite sequence of equidistant samples (a sample‐train) of a periodic signal can be identified with a point in a multidimensional space. Such a point depends on the signal, the sampling period, and the starting time of the sequence.

Multitemporal Sampling Module for Real-Time Human Activity Recognition
IEEE Access, 2022 Human activity recognition, which recognizes human activities from time-series signals collected by sensors, is an important task in human-centered intelligent systems such as in healthcare and smart vehicles. In these applications, rapid response of the

Design of a novel CEM‐FRM‐based low‐complexity channelised radar transmitter
IET Radar, Sonar & Navigation, 2021 With the development of the radar technology, it is required that a radar has wider bandwidth and can transmit multiple signals simultaneously. The polyphase digital channelised transmitter structure can transmit multiple signals simultaneously and ...

Transfer Learning for Event Detection From PMU Measurements With Scarce Labels
IEEE Access, 2021 Event detection in electrical grids is a challenging problem for machine learning methods due to spatiotemporally nonstationary systems and the inability to automate event labeling in high-volume data such as PMU measurements.

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