NOMA-Based IoT Networks: Impulsive Noise Effects and Mitigation
IEEE Communications Magazine, 2020The rise of the Internet of Things (IoT) presents important challenges for future radio networks. Non-orthogonal multiple access (NOMA), which allows the network to support more than one user per orthogonal resource element, was recently proposed as a ...

The phenomenon of impulsive noise is generated by Partial discharge (PD) sources in high-voltage substations. A PD generates a current impulse, acoustic noise, visible and ultraviolet (UV) light and electromagnetic radiation , and accordingly its presence can be detected via several measurement methods.

IEEE Transactions on Circuits and Systems Part 1: Regular Papers, 2020
Previous studies have shown that impulsive noise can weaken the performance of power line communication (PLC). Though DCSK can improve the performance in an order of magnitude comparing to the direct sequence differential phase shift keying (DS-DPSK), it

Digital images are often corrupted by various types of noises amongst which impulse noise is most prevalent. Impulse noise appears during transmission and/or acquisition of images. Intrusion of impulse noise degrades the quality of the image and causes the loss of fine image details.

A TV-log nonconvex approach for image deblurring with impulsive noise
Signal Processing, 2020In this paper, we study the image deblurring with impulsive noise problem. In order to find a high quality recovery solution, we propose a nonconvex optimization model that combines total variation regularization and nonconvex log penalty for data ...

Are Impulse Responses Gaussian Noises?
The Journal of the Acoustical Society of America, 2011Many years ago, Manfred Schroeder proved that transfer functions in rooms follow complex Gaussian distributions. This property was extended to impulse responses by the author, following a suggestion by Moorer for simulating impulse responses. More recently, several authors have checked again the later property with modern signal analysis tools.

DOA Estimation for CD Sources by Complex Cyclic Correntropy in an Impulsive Noise Environment
IEEE Communications Letters, 2020Impulsive noise degrades the performance of direction-of-arrival (DOA) estimation methods since the optimization for subspace-like techniques relies on an assumption of Gaussianity.

Impulsive Noises in Restaurants
The Journal of the Acoustical Society of America, 1967In work reported earlier, the authors examined the speech component of the restaurant-noise environment and developed a design method for achieving the required acoustic criteria. In the recent work presented here, they have expanded their analysis of the noise environment to include sounds such as dish and silverware clatter and other impact sounds.
