Learning Sparsifying Transforms for mmWave Communication via -Norm Maximization
Sueda Taner, Christoph Studer
The high directionality of wave propagation at millimeter-wave (mmWave) carrier frequencies results in only a small number of significant transmission paths between user equipments…
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…
Cauchy-Schwarz Regularizers
Sueda Taner, Ziyi Wang, Christoph Studer
We introduce a novel class of regularization functions, called Cauchy-Schwarz (CS) regularizers, which can be designed to induce a wide range of properties in solution vectors of o…
