Adaptive weighting for estimation of the mean of the merged measurement for multi‐target bearing tracking

open access: yesElectronics Letters, 2021
In multi‐target tracking, sensor with finite resolution generates merged measurements, which means that a group of targets might produce only one measurement, and such phenomenon could lead to degraded tracking performance if it is not considered.

Fractional‐order complex correntropy algorithm for adaptive filtering in α‐stable environment

open access: yesElectronics Letters, 2021
In adaptive filtering applications, the Gaussian distribution cannot be used to model the signal/noise with frequent spikes accurately. In fact, the rational model to simulate the behaviour of such signal/noise is the α‐stable distribution process.

Filtered Variation method for denoising and sparse signal processing [PDF]

open access: yes2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2012
We propose a new framework, called Filtered Variation (FV), for denoising and sparse signal processing applications. These problems are inherently ill-posed. Hence, we provide regularization to overcome this challenge by using discrete time filters that are widely used in signal processing.

Multi‐sensor particle filtering with multi‐step randomly delayed measurements

open access: yesIET Science, Measurement & Technology, 2021
This paper develops particle filtering for multi‐sensor systems with randomly delayed measurements, where the general case that random delay can be multi‐step rather than one‐step or two‐step is considered.

Frequency Domain Filtering Method for SSVEP-EEG Preprocessing

open access: yesIEEE Transactions on Neural Systems and Rehabilitation Engineering, 2023
Steady-state visual evoked potential (SSVEP) signal collected from the scalp typically contains other types of electric signals, and it is important to remove these noise components from the actual signal by application of a pre-processing step for ...
