Dimming Space-Time Code (DSTC) for Visible Light Communication with Semi-Blind Detection
Igor S. C. Rodrigues, Leandro R. Ximenes, André L. F. de Almeida
Visible light communication (VLC) provides a unified framework for wireless data transmission and illumination, but its practical deployment requires transmission schemes that join…
Time-Varying Parametric Channel Estimation With CP Decomposition Tensor Processing
Enrique T. R. Pinto, André L. F. de Almeida, Markku Juntti
Integrated sensing and communications (ISAC) is a key use case for sixth-generation (6G) wireless systems, where parametric channel estimation (PCE) plays a central role in enablin…
Uplink Channel Estimation for Multi-User MISO Systems Assisted by a Fluid Reconfigurable Intelligent Surface
Amarilton L. Magalhães, André L. F. de Almeida, George C. Alexandropoulos
Fluid reconfigurable intelligent surfaces (FRISs) have recently emerged as a promising paradigm for wireless communications, wherein the reflecting elements can dynamically select…
Multi-Target Estimation via Tensor Decomposition for Beyond Diagonal RIS-Aided Bistatic Sensing
Kenneth Benício, André L. F. de Almeida, Fazal-E Asim +4
We investigate the performance of beyond-diagonal reconfigurable intelligent surfaces (BD-RIS) for bistatic MIMO multi-target sensing using a two-stage tensor Doppler-delay-angle e…
Semi-Blind Receivers for RIS-Aided Fluid Antenna Systems
Josué V. de Araújo, Gilderlan T. de Araújo, André L. F. de Almeida
Reconfigurable intelligent surfaces (RISs) and fluid antennas (FAs) are key technologies for enhancing spatial degrees of freedom in future wireless networks. However, channel acqu…
PARAFAC-Based Channel Estimation for Beyond Diagonal Reconfigurable Surfaces
Gilderlan Tavares de Araújo, Bruno Sokal, André L. F. de Almeida
Channel estimation is a central bottleneck in BD-RIS-assisted MIMO systems. The richer inter-element coupling that enables large performance gains also makes training and hardware…
