Decoupled Delay-Doppler and Angle Estimation in BD-RIS Sensing via Nested Tucker Decomposition
Kenneth BenÃcio, 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…

Structured Channel Estimation for RIS-Assisted THz Communications
Fazal-E-Asim, Bruno Sokal, André L. F. de Almeida +2
This paper proposes tensor-based channel estimation for reconfigurable intelligent surface (RIS)-assisted communication networks. We exploit the inherent geometrical structure of t…
