Uplink Multi-User MIMO Implementation in OpenAirInterface
Utku Uçak, Fariba Armandoust, Matthias Mehlhose +4
Cell-Free Multiple-Input Multiple-Output (MIMO) and Open Radio Access Network (O-RAN) have been active research topics in the wireless communication community in recent years. As a…
Digital Post-Distortion Architectures for Nonlinear Power Amplifiers: Volterra and Kernel Methods
Daniel Schäufele, Jochen Fink, Renato L. G. Cavalcante +1
In modern 5G user equipments (UEs), the power amplifier (PA) contributes significantly to power consumption during uplink transmissions, especially in cell-edge scenarios. While re…
CISSIR: Beam Codebooks with Self-Interference Reduction Guarantees for Integrated Sensing and Communication Beyond 5G
Rodrigo Hernangómez, Jochen Fink, Renato L. G. Cavalcante +1
We propose a beam codebook design for integrated sensing and communication (ISAC) that reduces self-interference (SI) to alleviate analog distortion. Our optimization framework, wh…
Optimized Detection with Analog Beamforming for Monostatic Integrated Sensing and Communication
Rodrigo Hernangómez, Jochen Fink, Renato L. G. Cavalcante +2
In this paper, we formalize an optimization framework for analog beamforming in the context of monostatic integrated sensing and communication (ISAC), where we also address the pro…
Superiorized Adaptive Projected Subgradient Method with Application to MIMO Detection
Jochen Fink, Renato L. G. Cavalcante, Slawomir Stanczak
In this paper, we show that the adaptive projected subgradient method (APSM) is bounded perturbation resilient. To illustrate a potential application of this result, we propose a s…
Multi-Group Multicast Beamforming by Superiorized Projections onto Convex Sets
Jochen Fink, Renato L. G. Cavalcante, Slawomir Stanczak
In this paper, we propose an iterative algorithm to address the nonconvex multi-group multicast beamforming problem with quality-of-service constraints and per-antenna power constr…
