Receiver design of sparse Bayesian learning based MIMO-OFDM power line communication system

open access: yesDianxin kexue, 2022
The rich impulsive noise in the power line channel poses a huge challenge to the design of MIMO-OFDM transceiver.To solve this problem, a design scheme that can jointly estimate the channel and impulsive noise was proposed, which exploited the parametric

An adaptive dynamically weighted median filter for impulse noise removal

open access: yesEURASIP Journal on Advances in Signal Processing, 2017
A new impulsive noise removal filter, adaptive dynamically weighted median filter (ADWMF), is proposed. A popular method for removing impulsive noise is a median filter whereas the weighted median filter and center weighted median filter were also ...

Joint channel and impulsive noise estimation method for OFDM systems

open access: yesTongxin xuebao, 2018
Aiming at the impulsive noise occurring in OFDM systems,an impulsive noise mitigation algorithm based on compressed sensing theory was proposed.The proposed algorithm firstly treated the channel impulse response and the impulsive noise as a joint sparse ...

Joint Channel Estimation, Data Decoding, and Group-Sparse Impulsive Noise Estimation for Slowly Time-Varying Single Carrier Underwater Acoustic Communications

open access: yesIEEE Access
The Gaussian noise assumption is usually made for slowly time-varying underwater acoustic communication (UWAC) systems, which is entirely adequate for most cases.

Far-Field Effects of Impulsive Noise on Coastal Bottlenose Dolphins

open access: yesFrontiers in Marine Science, 2021
Increasing levels of anthropogenic underwater noise have caused concern over their potential impacts on marine life. Offshore renewable energy developments and seismic exploration can produce impulsive noise which is especially hazardous for marine ...

Modelling impulsive noise in indoor powerline communication systems

open access: yesSignal, Image and Video Processing, 2020
Powerline communication (PLC) is an emerging technology that has an important role in smart grid systems. Due to making use of existing transmission lines for communication purposes, PLC systems are subject to various noise effects. Among those, the most

Space-time block codes with rate >= 1 for power line channels [PDF]

open access: yes, 2002
In this paper, the utilisation of space-time block codes (STBC) for high-speed communications over power line channels (PLC) affected by quasi-static flat Rayleigh fading and additive man-made asynchronous impulsive noise is presented.

Impulsive Noise-Resilient Subband Adaptive Filter

open access: yes, 2016
We present a new subband adaptive filter (R-SAF) which is robust against impulsive noise in system identification. To address the vulnerability of adaptive filters based on the L2-norm optimization criterion against impulsive noise, the R-SAF comes from ...

Complexity Analysis of Bubble Plumes in Power Law Fluids Based on Chaos Theory

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In order to reveal the complexity of the internal flow of bubble plume in power law fluid, the flow characteristics and chaotic characteristics of plume are studied by experiment and theory. The chaotic characteristic parameters (correlation dimension D, K entropy, and Lyapunov exponent λ) of gas velocity under different superficial gas ...

Beyond the Outburst: Charting a New Frontier for Understanding and Treating Irritability in Autistic Adults

open access: yesAutism Research, EarlyView.
ABSTRACT Irritability is a prevalent and impairing feature associated with autism, yet remains poorly understood, particularly in adults. Drawing heavily on insights translated from pediatric and transdiagnostic literatures, we propose that irritability in autistic individuals often reflects a psychophysiological stress or threat response, rooted in a ...
