Discrete Signal Processing on Graphs: Sampling Theory [PDF]

open access: yesIEEE Transactions on Signal Processing, 2015
We propose a sampling theory for signals that are supported on either directed or undirected graphs. The theory follows the same paradigm as classical sampling theory. We show that the perfect recovery is possible for graph signals bandlimited under the graph Fourier transform, and the sampled signal coefficients form a new graph signal, whose ...

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.

Graph Signal Processing: Modulation, Convolution, and Sampling

open access: green, 2019
To analyze data supported by arbitrary graphs G, DSP has been extended to Graph Signal Processing (GSP) by redefining traditional DSP concepts like shift, filtering, and Fourier transform among others. This paper revisits modulation, convolution, and sampling of graph signals as appropriate natural extensions of the corresponding DSP concepts.

Graph Signal Processing: Dualizing GSP Sampling in the Vertex and Spectral Domains [PDF]

open access: yesIEEE Transactions on Signal Processing, 2021
Vertex based and spectral based GSP sampling has been studied recently. The literature recognizes that methods in one domain do not have a counterpart in the other domain.

Pulse-Doppler Signal Processing with Quadrature Compressive Sampling [PDF]

open access: greenIEEE Transactions on Aerospace and Electronic Systems, 2013
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.

Localized nonlinear functional equations and two sampling problems in signal processing

open access: greenAdvances in Computational Mathematics, 2013
Let 1 ≤ p ≤ ∞. In this paper, we consider solving a nonlinear functional equation f (x) = y, where x, y belong to ℓpand f has continuous bounded gradient in an inverse-closed subalgebra of ℬ (ℓ2), the Banach algebra of all bounded linear operators on the
