A new approach for the reassignment of time-frequency representations
TL;DR: The results of numerical analysis show that the proposed method is capable of achieving significantly higher concentration of signals in the time-frequency domain in comparison to the spectrogram and the traditional reassignment method.
Proceedings ArticleDOI
A unified approach for the estimation of instantaneous frequency and its derivatives for non-stationary signals analysis
TL;DR: A unified approach for the estimation of the first three phase derivatives of non-stationary signals is proposed in this paper, inspired by the concepts of complex analysis theory.
Proceedings ArticleDOI
Application of Multitaper Analysis to wireless communications problems
Serguei Primak,Ervin Sejdic +1 more
TL;DR: The paper presents two novel applications of Thomson Multitaper Analysis: a wideband simulator of a double mobile MIMO channel could be developed based on geometrical channel model and modification of Discrete Prolate Spheroidal Sequences could be used to better estimation of sparse channels.
Proceedings ArticleDOI
An EEG and fTCD based BCI for control
TL;DR: This work aims to develop a noninvasive hybrid BCI relying on two imaging modalities: Electroencephalography (EEG) and functional transcranial Doppler sonography (fTCD) to be sufficiently robust and accurate to be operated in a real-life environment.

Correlating Tri-Accelerometer Swallowing Vibrations and Hyoid Bone Movement in Patients With Dysphagia
TL;DR: This paper investigates the correlation between the swallowing vibrations recorded by the tri-axial accelerometer and hyoid bone kinetics observed in video-fluoroscopic swallow imaging studies, and investigates this correlation with vibration signals measured in the medial-lateral plane of accelerometry.
