Adaptive blind equalization for multi‐level QAM signals in impulsive noise environment

IET Communications, 2022
A maximum correntropy criterion‐blind clustering multi‐modulus algorithm (MCC‐BCMMA) is proposed to equalize multi‐level quadrature amplitude modulation (QAM) channels in impulsive noise environment.

An adaptive kernel width convex combination method for maximum correntropy criterion

Journal of the Brazilian Computer Society, 2021
Recently, the maximum correntropy criterion (MCC) has been successfully applied in numerous applications regarding nonGaussian data processing. MCC employs a free parameter called kernel width, which affects the convergence rate, robustness, and steady ...

Improved Robust High-Degree Cubature Kalman Filter Based on Novel Cubature Formula and Maximum Correntropy Criterion with Application to Surface Target Tracking

Journal of Marine Science and Engineering, 2022
Robust nonlinear filtering is an important method for tracking maneuvering targets in non-Gaussian noise environments. Although there are many robust filters for nonlinear systems, few of them have ideal performance for mixed Gaussian noise and non ...

Parameter estimation based on novel enhanced self‐learning particle swarm optimization algorithm with Levy flight for PMSG

IET Generation, Transmission &Distribution, Volume 17, Issue 5, Page 1111-1122, March 2023., 2023
A novel parameter estimation method is proposed for the permanent magnet synchronous generator (PMSG), which is implemented by an enhanced self‐learning particle swarm optimization algorithm with Levy flight (SLPSO), and the problem of lower parameter estimation precision of standard PSO is obviated.

Robust localization based on non‐parametric kernel technique

Electronics Letters, Volume 58, Issue 22, Page 850-852, October 2022., 2022
Abstract Parametric approaches are primarily used in the context of robust localization. However, the localization performance is degraded when there is a mismatch between the assumed model and the actual situation. To circumvent this problem, in this letter, a robust weighted least squares (WLS) method based on the non‐parametric kernel density ...
