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).…
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…
Tensor-Based Channel Estimation and Data-Aided Tracking in IRS-Assisted MIMO Systems
Kenneth B. A. Benicio, André L. F. de Almeida, Bruno Sokal +3
This letter proposes a model for symbol detection in the uplink of IRS-assisted networks in the presence of channel aging. During the first stage, we model the received pilot signa…
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…
Structured Channel Estimation for RIS-Assisted THz Communications
Fazal-E-Asim, Bruno Sokal, André L. F. de Almeida +2
This paper proposes tensor-based channel estimation for reconfigurable intelligent surface (RIS)-assisted communication networks. We exploit the inherent geometrical structure of t…
