RIS-Based DOA Estimation for Communication-Assisted Sensing Systems Under Hardware Impairments
IEEE Open Journal of Vehicular TechnologyReconfigurable intelligent surface (RIS)-based localization has received significant attention in wireless communication systems due to its potential for enabling non-line-of-sight (NLoS) wireless sensing.

Invertibility properties of matrix wiener‐hopf plus Hankel integral operators
Mathematical Modelling and Analysis, 2008 We consider matrix Wiener‐Hopf plus Hankel operators acting between Lebesgue spaces on the real line with Fourier symbols presenting some even properties (which in particular include unitary matrix‐valued functions), and also with Fourier symbols which ...

Analysis of Cardiosignals Cohesion based on Hankel Matrix
Elektronika ir Elektrotechnika, 2008 A big part of heart disease diagnostics criteria is collected by registration and analysis of cardio signals that show electric heart activity disturbance (ECG) and hemodynamic and mechanic activity changes as impedance cardiograms (ICG) and seismocardiograms (SCG).

Modal parameter identification from output data only
MATEC Web of Conferences, 2015 To identify the modal parameters of a vibrating system from output data only we use a state space model and usually two approaches are considered: the block Hankel matrix and its shifted version and the block observability matrix and its shifted version.

Numerical Approach for the Frequency-Weighted Hankel-Norm Approximation [PDF]
, 2001 We derive new projection formulas for the model reduction method based on the frequency-weighted Hankel norm approximation (FWHNA). These formulas extend the applicability of the FWHNA method to frequency weights expressed as antistable right/left ...

On the Frobenius Norm of Commutator of Cauchy-Hankel Matrix and Exchange Matrix
Turkish Journal of Mathematics and Computer ScienceThis paper gives upper and lower bounds for the Frobenius norm of the commutator of the exchange matrix and the Cauchy-Hankel matrix of the form $H_n=\left(\dfrac{2}{1+2(i+j)}\right)_{i,j=1}^n$.
