Enhanced channel estimation for double RIS-aided MIMO systems using coupled tensor decomposition
Gerald C. Nwalozie, Andre L. F. de Almeida, Martin Haardt
In this paper, we consider a double-RIS (D-RIS)-aided flat-fading MIMO system and propose an interference-free channel training and estimation protocol, where the two single-reflec…
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…
Channel Estimation for Beyond Diagonal RIS via Tensor Decomposition
André L. F. de Almeida, Bruno Sokal, Hongyu Li +1
This paper addresses the channel estimation problem for beyond diagonal reconfigurable intelligent surface (BD-RIS) from a tensor decomposition perspective. We first show that the…
