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.

Design of Switched Quantizers and Speech Coding Based on Quasi-Logarithmic Compandor

open access: yesElektronika ir Elektrotechnika, 2018
This article investigates switched quantizers for speech signal depicted with Gaussian probability density function (PDF). Gaussian PDF is better for smaller frame lengths that are represented here.

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

Noise reduction in speech signal processing by neural network and vector quantization [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1988
The autocorrelation function provides basic data for speech signal processing by the linear prediction algorithm. The first step toward developing a practical speech signal processing technique is noise reduction in the autocorrelation function of speech corrupted by noise.

Signal Processing of Coast-Ship Bistatic High-Frequency Surface-Wave Radar Using One-Bit Quantized Measurement [PDF]

open access: yesIEEE Access, 2020
The feasibility of one-bit quantization in coast-ship bistatic high-frequency surface-wave radar (HFSWR) is mainly discussed in order to enjoy the advantages of simplicity, low cost and low power consumption. Our theoretical derivation shows that the received signal after one-bit quantization can be expressed as a linear combination of infinite ...

Demodulating BOC signals using compressive signal processing

open access: yesDianzi Jishu Yingyong, 2019
In order to lower the sampling frequency of binary offset carrier(BOC) signal, a BOC signal demodulation scheme based on compressive signal processing is proposed.

Switched Scalar Quantization with Adaptation Performed on both the Power and the Distribution of Speech Signal [PDF]

open access: yesTelfor Journal, 2011
This paper analyzes the models for switching scalar quantization of a source with the Laplacian and Gaussian distribution. We have analyzed the results of real telephone speech and proposed a model of switching scalar quantization, which, in addition to ...
