Dilated POCS: Minimax Convex Optimization

open access: yesIEEE Access, 2023
Alternating projection onto convex sets (POCS) provides an iterative procedure to find a signal that satisfies two or more convex constraints when the sets intersect.

Stable signal recovery in compressed sensing with a structured matrix perturbation [PDF]

open access: yes, 2012
The sparse signal recovery in the standard compressed sensing (CS) problem requires that the sensing matrix be known a priori. Such an ideal assumption may not be met in practical applications where various errors and fluctuations exist in the sensing ...

Lipschitz Learning for Signal Recovery

open access: yesCoRR, 2019
We consider the recovery of signals from their observations, which are samples of a transform of the signals rather than the signals themselves, by using machine learning (ML). We will develop a theoretical framework to characterize the signals that can be robustly recovered from their observations by an ML algorithm, and establish a Lipschitz ...

Methods for early recognition of OFDM data [PDF]

open access: yesКомпьютерная оптика, 2020
A technique of early recognition (recovery) of data transmitted using OFDM technology by an incompletely received signal is considered. Theoretically, this approach is able to increase the speed of information transfer, as well as the resistance of the ...

Compressive Sensing via Variational Bayesian Inference under Two Widely Used Priors: Modeling, Comparison and Discussion

open access: yesEntropy, 2023
Compressive sensing is a sub-Nyquist sampling technique for efficient signal acquisition and reconstruction of sparse or compressible signals. In order to account for the sparsity of the underlying signal of interest, it is common to use sparsifying ...

Joint Channel Estimation and Signal Recovery in RIS-Assisted Multi-User MISO Communications [PDF]

open access: yesIEEE Wireless Communications and Networking Conference, 2020
Reconfigurable Intelligent Surfaces (RISs) have been recently considered as an energy-efficient solution for future wireless networks. Their dynamic and low-power configuration enables coverage extension, massive connectivity, and low-latency ...

Trainable ISTA for Sparse Signal Recovery [PDF]

open access: yesIEEE Transactions on Signal Processing, 2018
In this paper, we propose a novel sparse signal recovery algorithm called the trainable iterative soft thresholding algorithm (TISTA). The proposed algorithm consists of two estimation units: a linear estimation unit and a minimum mean squared error ...

Non-Bayesian Estimation Framework for Signal Recovery on Graphs [PDF]

open access: yesIEEE Transactions on Signal Processing, 2020
Graph signals arise from physical networks, such as power and communication systems, or as a result of a convenient representation of data with complex structure, such as social networks.

Sampling and Recovery of Graph Signals [PDF]

open access: yes, 2018
The aim of this chapter is to give an overview of the recent advances related to sampling and recovery of signals defined over graphs. First, we illustrate the conditions for perfect recovery of bandlimited graph signals from samples collected over a selected set of vertexes. Then, we describe some sampling design criteria proposed in the literature to
