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…
Low-Complexity Joint Active and Passive Beamforming Design for IRS-Assisted MIMO
Yuri S. Ribeiro, Fazal E-Asim, André L. F de Almeida +2
In this letter, we consider an intelligent reflecting surface (IRS)-assisted multiple input multiple output (MIMO) communication and we optimize the joint active and passive beamfo…
Two-Dimensional Channel Parameter Estimation for IRS-Assisted Networks
Fazal-E-Asim, André L. F. de Almeida, Bruno Sokal +2
This paper proposes a pilot decoupling-based two-dimensional channel parameter estimation method for intelligent reflecting surface (IRS)-assisted networks. We exploit the combined…
Channel Estimation in RIS-Assisted MIMO Systems Operating Under Imperfections
Paulo R. B. Gomes, Gilderlan T. de Araújo, Bruno Sokal +3
Reconfigurable intelligent surface is a potential technology component of future wireless networks due to its capability of shaping the wireless environment. The promising MIMO sys…
Joint Channel Estimation / Data Detection in MIMO-FBMC/OQAM Systems - A Tensor-Based Approach
Eleftherios Kofidis, Christos Chatzichristos, Andre L. F. de Almeida
Filter bank-based multicarrier (FBMC) systems are currently being considered as a prevalent candidate for replacing the long established cyclic prefix (CP)-based orthogonal frequen…
