OTFS Channel Estimation Utilizing Sparse Bayesian Generative Modelling
Louis Anseaume, Benedikt Böck, Franz Weißer +1
One of the key challenges of future wireless communication systems is ensuring reliability in high-speed mobile scenarios, where accurate recovery of channel state information (CSI…
Lightweight Beam Index Map Using Coupled Gaussian Mixture Models
Amar Kasibovic, Franz Weißer, Wolfgang Utschick
This paper addresses the beam alignment problem in MIMO systems from a decentralized, mobile terminal (MT)-centric perspective. We propose a lightweight machine learning approach t…
Joint Access Point Selection and Precoder Design under Statistical CSI
Tim N. Faisst, Franz Weißer, Wolfgang Utschick
This work addresses joint access point (AP) selection and precoding for sum-rate maximization under statistical channel state information (CSI) in multi-AP multi-user systems. To t…
Efficient Channel Prediction based on Gram-Square-Root Factorization using GMMs
Kathrin Klein, Amar Kasibovic, Michael Joham +2
Accurate channel state information (CSI) is critical for downlink (DL)-multi-user (MU)-multiple-input multiple-output (MIMO) systems, where feedback delays and mobility can degrade…
Context-Aware CSI Prediction for Access Point Selection Utilizing Conditional VAEs
Franz Weißer, Amar Kasibovic, Wolfgang Utschick
Indoor wireless communication environments are strongly influenced by dynamic conditions, which affect channel state information (CSI) and, consequently, the precoding strategy and…
On the Optimality of Rate Balancing for Max-Min Fair Multicasting
Sadaf Syed, Wolfgang Utschick, Michael Joham
The max-min fair (MMF) multicasting problem is known to be NP-hard. In this work, we analytically derive the optimal solution to this NP-hard problem and establish the equivalence…
