An Optimization-Based User Scheduling Framework for Multiuser MIMO Systems
Victoria Palhares, Christoph Studer
Resource allocation is a key factor in multiuser (MU) multiple-input multiple-output (MIMO) wireless systems to provide high quality of service to all user equipments (UEs). In con…
Weather Estimation for Integrated Sensing and Communication
Victoria Palhares, Artjom Grudnitsky, Silvio Mandelli
One of the key features of sixth-generation (6G) mobile communications will be integrated sensing and communication (ISAC). While the main goal of ISAC in standardization efforts i…
CSI2Vec: Towards a Universal CSI Feature Representation for Positioning and Channel Charting
Victoria Palhares, Sueda Taner, Christoph Studer
Natural language processing techniques, such as Word2Vec, have demonstrated exceptional capabilities in capturing semantic and syntactic relationships of text through vector embedd…
Channel Charting in Real-World Coordinates with Distributed MIMO
Sueda Taner, Victoria Palhares, Christoph Studer
Channel charting is an emerging self-supervised method that maps channel-state information (CSI) to a low-dimensional latent space (the channel chart) that represents pseudo-positi…
LoFi User Scheduling for Multiuser MIMO Wireless Systems
Alexandra Gallyas-Sanhueza, Gian Marti, Victoria Palhares +2
We propose new low-fidelity (LoFi) user equipment (UE) scheduling algorithms for multiuser multiple-input multiple-output (MIMO) wireless communication systems. The proposed method…
High Dynamic Range mmWave Massive MU-MIMO with Householder Reflections
Victoria Palhares, Gian Marti, Oscar Castañeda +1
All-digital massive multiuser (MU) multiple-input multiple-output (MIMO) at millimeter-wave (mmWave) frequencies is a promising technology for next-generation wireless systems. Low…
Channel Charting in Real-World Coordinates
Sueda Taner, Victoria Palhares, Christoph Studer
Channel charting is an emerging self-supervised method that maps channel state information (CSI) to a low-dimensional latent space, which represents pseudo-positions of user equipm…
Beam Alignment for the Cell-Free mmWave Massive MU-MIMO Uplink
Jannik Brun, Victoria Palhares, Gian Marti +1
Millimeter-wave (mmWave) cell-free massive multi-user (MU) multiple-input multiple-output (MIMO) systems combine the large bandwidths available at mmWave frequencies with the impro…
An Optimization-Based User Scheduling Framework for mmWave Massive MU-MIMO Systems
Victoria Palhares, Christoph Studer
We propose a novel user equipment (UE) scheduling framework for millimeter-wave (mmWave) massive multiuser (MU) multiple-input multiple-output (MIMO) wireless systems. Our framewor…
Robust MMSE Precoding and Power Allocation for Cell-Free Networks
V. M. T. Palhares, A. Flores, R. C. de Lamare
We consider the downlink of a cell-free massive multiple-input multiple-output (MIMO) system with \textcolor{red}{single}-antenna access points (APs) and single-antenna users. An i…
Iterative Access Point Selection, MMSE Precoding and Power Allocation for Cell-Free Networks
V. Palhares, A. R. Flores, R. C. de Lamare
In this work, we propose iterative access point (AP) selection (APS), linear minimum mean-square error (MMSE) precoding and power allocation techniques for Cell-Free Massive multip…
