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…
Multi-Target Estimation via Tensor Decomposition for Beyond Diagonal RIS-Aided Bistatic Sensing
Kenneth Benício, André L. F. de Almeida, Fazal-E Asim +4
We investigate the performance of beyond-diagonal reconfigurable intelligent surfaces (BD-RIS) for bistatic MIMO multi-target sensing using a two-stage tensor Doppler-delay-angle e…
RIS-Assisted Sensing: A Nested Tensor Decomposition-Based Approach
Kenneth Benício, Fazal-E-Asim, Bruno Sokal +4
We study a monostatic multiple-input multiple-output sensing scenario assisted by a reconfigurable intelligent surface using tensor signal modeling. We propose a method that exploi…
Tensor-based modeling/estimation of static channels in IRS-assisted MIMO systems
Kenneth B. A. Benício, André L. F. de Almeida, Bruno Sokal +3
This paper proposes a tensor-based parametric modeling and estimation framework in multiple-input multiple-output (MIMO) systems assisted by intelligent reflecting surfaces (IRSs).…
