Joint Channel and Symbol Estimation for RIS-Assisted Fluid Antenna Systems
Josué V. de Araújo, Daniel C. Alcantara, Gilderlan T. de Araújo +1
This paper addresses joint channel and symbol estimation in reconfigurable intelligent surface (RIS)-aided multiuser uplink systems with fluid antennas (FAs) at the base station. W…
Channel Estimation for Movable Intelligent Surface
Daniel C. Alcantara, Josué V. de Araújo, Gilderlan T. de Araújo +1
This paper proposes a tensor-based channel estimation framework for an uplink MIMO system assisted by a movable intelligent surface. The considered architecture combines a fixed tr…
Reducing Complexity of Data-Aided Channel Estimation in RIS-Assisted Communications
Amarilton Lopes Magalhães, André Lima Férrer de Almeida, Gilderlan Tavares de Araújo
We consider the data-aided channel estimation (CE) problem in a reconfigurable intelligent surface (RIS)-assisted wireless communication system, where the channel and information s…
Channel Estimation for Intelligent Reflecting Surface Assisted MIMO Systems: A Tensor Modeling Approach
Gilderlan T. de Araújo, André L. F. de Almeida, Rémy Boyer
Intelligent reflecting surface (IRS) is an emerging technology for future wireless communications including 5G and especially 6G. It consists of a large 2D array of (semi-)passive…
