Deconstructing the Composite Channel for Beyond Diagonal RIS: Channel Estimation and Beamforming Design
Fazal-E Asim, André L. F. de Almeida, Bruno Sokal +2
As beyond-diagonal reconfigurable intelligent surfaces (BD-RISs) gain increasing attention in high-frequency wireless communications, accurate and scalable channel-estimation metho…
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…
Low-Complexity Tensor-Based Monostatic Sensing for IRS-Assisted Communication Systems
Kenneth B. A. BenÃcio, Bruno Sokal, André L. F. de Almeida +3
This paper proposes a tensor-based parameter estimation algorithm for sensing in an intelligent reflecting surface-assisted system. We present a higher-order singular value decompo…
Multi-Target Estimation via Tensor Decomposition for Beyond Diagonal RIS-Aided Bistatic Sensing
Kenneth BenÃcio, 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…
Living Off the Grid: Continuous Range-Angle Super-Resolution for Near-Field XL-MIMO
Sajad Daei, Gabor Fodor, Mikael Skoglund
Near-field extremely large multiple input multiple output (XL-MIMO) breaks the assumptions that make classical super-resolution effective: the receiver acquires only a limited set…
Mobility Management in Integrated Sensing and Communications Networks
Yuri S. Ribeiro, Behrooz Makki, Andre L. F. de Almeida +1
The performance of the integrated sensing and communication (ISAC) networks is considerably affected by the mobility of the transceiver nodes, user equipment devices (UEs) and the…
