Decoupled Delay-Doppler and Angle Estimation in BD-RIS Sensing via Nested Tucker Decomposition
Kenneth Benício, André L. F. de Almeida, Fazal-E-Asim +4
We study single-target localization in a group-connected beyond-diagonal reconfigurable intelligent surface (BD-RIS)-assisted monostatic network with K element groups. We propose a…

PARAFAC-Based Time-Varying Channel Estimation for IRS-Aided Communications
Kenneth B. A. Benício, André L. F. de Almeida, Bruno Sokal +3
This paper proposes a tensor-based parametric channel estimation technique for IRS-assisted communication systems with time-varying channel parameters. We exploit the multidimensio…
