A system for compressive sensing signal reconstruction [PDF]

open access: yesIEEE EUROCON 2017 -17th International Conference on Smart Technologies, 2017
An architecture for hardware realization of a system for sparse signal reconstruction is presented. The threshold based reconstruction method is considered, which is further modified in this paper to reduce the system complexity in order to provide easier hardware realization.

Gradient Projection with Approximate L0 Norm Minimization for Sparse Reconstruction in Compressed Sensing

open access: yesSensors, 2018
In the reconstruction of sparse signals in compressed sensing, the reconstruction algorithm is required to reconstruct the sparsest form of signal. In order to minimize the objective function, minimal norm algorithm and greedy pursuit algorithm are most ...

A Novel Approach for Cancelation of Nonaligned Inter Spreading Factor Interference in LoRa Systems

open access: yesIEEE Open Journal of the Communications Society, 2022
Long Range (LoRa) has become a key enabler technology for low power wide area networks. However, due to its ALOHA-based medium access scheme, LoRa has to cope with collisions that limit the capacity and network scalability.

A Sensor Fault-Tolerant Accident Diagnosis System

open access: yesSensors, 2020
Emergency situations in nuclear power plants are accompanied by an automatic reactor shutdown, which gives a big task burden to the plant operators under highly stressful conditions. Diagnosis of the occurred accident is an essential sequence for optimum

A Modified Spectral Gradient Projection Method for Solving Non-Linear Monotone Equations With Convex Constraints and Its Application

open access: yesIEEE Access, 2020
In this paper, we propose a derivative free algorithm for solving non-linear monotone equations with convex constraints. The proposed algorithm combines the method of spectral gradient and the projection method.

Guided Signal Reconstruction Theory

open access: yesCoRR, 2017
An axiomatic approach to signal reconstruction is formulated, involving a sample consistent set and a guiding set, describing desired reconstructions. New frame-less reconstruction methods are proposed, based on a novel concept of a reconstruction set, defined as a shortest pathway between the sample consistent set and the guiding set.

Exact CS Reconstruction Condition of Undersampled Spectrum-Sparse Signals

open access: yesJournal of Applied Mathematics, 2013
Compressive sensing (CS) reconstruction of a spectrum-sparse signal from undersampled data is, in fact, an ill-posed problem. In this paper, we mathematically prove that, in certain cases, the exact CS reconstruction of a spectrum-sparse signal from ...
