An enhanced normalized step-size algorithm based on adjustable nonlinear transformation function for active control of impulsive noise

, 2021
Impulsive noise is widely distributed in various scenarios and becomes an important challenge for the practical applications of active noise control (ANC) system.

Detectors of the impulsive noise and new effective filters for the impulsive noise reduction

SPIE Proceedings, 2003
As it is known, the impulsive noise appears on the image in the form of randomly distributed pixels of random brightness. Impulses themselves usually differ much from the surrounding pixels in brightness. The main topic of the paper is the introduction of the new impulse detection criteria, and their application to such filters as median, rank-order ...

Robust DOA estimation for burst impulsive noise

Digit. Signal Process., 2021
This paper describes a robust sparse Bayesian learning approach for DOA estimation in the presence of impulsive noise. In practical situations, impulses in the noise often appear in bursts, resulting in structured rather than independent sparsity, which ...

Impulsive noise characterization at source

2008 1st IFIP Wireless Days, 2008
The noise characteristics of an indoor powerline network strongly influence the link capability to achieve high data rates. The appliances shared with PLC modems in the same powerline network generate noises, among them the impulsive ones which are the main source of interference which causes signal distortions leading to bit errors while data ...

Impulsive Noise Excision Using Robust Smoothing

IEEE Geoscience and Remote Sensing Letters, 2021
The impulsive noise originated from regional lightning discharges can dramatically degrade the performance of skywave over-the-horizon radar (OTHR) target detection with generally 10–20-dB increase of noise level in the Doppler domain. As a result, it is

Hazardous Exposure to Impulse Noise

The Journal of the Acoustical Society of America, 1968
This paper presents impulse-noise damage-risk criteria based on conclusions of independent British and American studies and on the work of other research workers in this field. Most of the studies that led to this criterion were performed with noise from small arms, but the criterion is general enough to permit assessment of most other types of impulse

Noise-induced neural impulses

European Biophysics Journal, 1986
The firing pattern of neural pulses often show the following features: the shapes of individual pulses are nearly identical and frequency independent; the firing frequency can vary over a broad range; the time period between pulses shows a stochastic scatter. This behaviour cannot be understood on the basis of a deterministic non-linear dynamic process,

DOA Estimation for Mixed Circular and Noncircular Coherently Distributed Sources Under Impulsive Noise

IEEE Transactions on Aerospace and Electronic Systems
In this study, we propose a method for direction of arrival (DOA) estimation of mixed circular and noncircular coherently distributed (CD) sources under impulsive noise.

A Robust DOA Estimator Based on Maximum Mixture Complex Correntropy for Noisy Input and Impulsive Noise

IEEE Transactions on Circuits and Systems - II - Express Briefs
Inspired by the robustness of maximum mixture complex correntropy (MMCC) to non-Gaussian and impulsive noises, an adaptive nulling antenna structure based MMCC adaptive filtering algorithm is presented in this brief to well solve the problem of direction
