KRLS post-distorter with adaptive kernel width for visible light communications

open access: yesOptics Express, 2023
As a viable supplement to the fifth generation wireless communication, visible light communications (VLC) with affluent spectrum resources can cater to the ever-increasing high speed data transmission demand. However, the nonlinear characteristics of light emitting diode (LED) can distort the transmitted signal in the VLC link, which damages the ...

An Improved Model for Kernel Density Estimation Based on Quadtree and Quasi-Interpolation

open access: yesMathematics, 2022
There are three main problems for classical kernel density estimation in its application: boundary problem, over-smoothing problem of high (low)-density region and low-efficiency problem of large samples.

Anisotropic Gaussian kernel adaptive filtering by Lie-group dictionary learning.

open access: yesPLoS ONE, 2020
The present paper proposes a novel kernel adaptive filtering algorithm, where each Gaussian kernel is parameterized by a center vector and a symmetric positive definite (SPD) precision matrix, which is regarded as a generalization of scalar width ...

Complex Correntropy with Variable Center: Definition, Properties, and Application to Adaptive Filtering

open access: yesEntropy, 2020
The complex correntropy has been successfully applied to complex domain adaptive filtering, and the corresponding maximum complex correntropy criterion (MCCC) algorithm has been proved to be robust to non-Gaussian noises.

A fixed point update for kernel width adaptation in information theoretic criteria [PDF]

open access: yes2010 IEEE International Workshop on Machine Learning for Signal Processing, 2010
This paper presents a fixed point update for adaptation of the kernel width parameter in information theoretic criteria. These criteria are typically non-parametric and require a kernel width parameter to be appropriately set. The kernel width sets the smoothing bandwidth for estimation of the probability distribution of the error and, consequently ...

Adaptive Doppler‐smoothed‐code bilateral kernel regression method for single‐frequency BeiDou receiver

open access: yesIET Radar, Sonar & Navigation, 2023
Currently, single‐frequency Global Navigation Satellite System (GNSS) receivers dominate maritime navigation units due to their simple structure and low cost but usually cannot meet the positioning requirements of Maritime Autonomous Surface Ship (MASS).

A novel algorithm of individual tree crowns segmentation considering three-dimensional canopy attributes using UAV oblique photos

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2022
Extracting the individual tree crowns (ITCs) information is significant to fine forest resource investigation and carbon storage estimation. UAV oblique photogrammetry (UOP) can obtain point cloud data with high density due to higher presence of overlap,
