On the behavior of EMD and MEMD in presence of symmetric alpha-stable noise [PDF]

, 2014
EmpiricalMode Decomposition (EMD) and its extended versions such as Multivariate EMD (MEMD) are data-driven techniques that represent nonlinear and non-stationary data as a sum of a finite zero-mean AM-FM components referred to as Intrinsic Mode ...

Joint Channel Estimation and Impulsive Noise Mitigation Method for OFDM Systems Using Sparse Bayesian Learning

IEEE Access, 2019
The impulsive noise can deteriorate sharply the performance of orthogonal frequency division multiplexing (OFDM) systems. In this paper, we propose a novel joint channel impulse response estimation and impulsive noise mitigation algorithm based on ...

Robust Non-Linear Active Function-Based FxRLS for Impulsive Active Noise Control

IEEE Access
Active Noise Control (ANC) is an effective technique for removing undesirable disturbances based on destructive interference between two noises (i.e., the superposition principle).

An adaptive algorithm, based on modified tanh non-linearity and fractional processing, for impulsive active noise control systems [PDF]

, 2017
This paper presents an adaptive algorithm for active control of noise sources that are of impulsive nature. The impulsive type sources can be better modeled as a stable distribution than the Gaussian.
