Learning of robust spectral graph dictionaries for distributed processing

open access: yesEURASIP Journal on Advances in Signal Processing, 2018
We consider the problem of distributed representation of signals in sensor networks, where sensors exchange quantized information with their neighbors. The signals of interest are assumed to have a sparse representation with spectral graph dictionaries ...

NDM: 1-Bit Delta-Sigma Converter with Non-Linear Loop [PDF]

open access: yesMATEC Web of Conferences, 2019
In this paper we propose to introduce a new processing scheme in the basic loop of a Delta Sigma (ΔΣ) analog-to-digital converter. This processing confers extra gains of the converter over both the quantization error and the channel noise.

Algorithm based on 2‐bit adaptive delta modulation and fractional linear prediction for Gaussian source coding

open access: yesIET Signal Processing, 2021
A novel 2‐bit adaptive delta modulation (ADM) algorithm is presented based on uniform scalar quantization and fractional linear prediction (FLP) for encoding the signals modelled by a Gaussian probability density function. The study focusses on two major
