Structured PARAFAC Channel Estimation for Flexible Intelligent Metasurface Receivers
Xi Han, Junqiao Chen, Yuansheng Zhang +2
Flexible intelligent metasurfaces (FIMs) create geometric diversity through aperture morphing, but their configuration-dependent responses complicate uplink channel estimation. Thi…
PARAFAC-Based Low-Latency Angular Tracking for RIS-Assisted Sensing
Kenneth Benício, André L. F. de Almeida, Bruno Sokal +3
This paper proposes adaptive tensor tracking for angular trajectories (ATTRACT), a structure-aware alternating least squares algorithm for low-latency target tracking in reconfigur…
Low-Complexity Tensor-Based Monostatic Sensing for IRS-Assisted Communication Systems
Kenneth B. A. Benício, 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…
