Performance Analysis of Cell-Free Massive MIMO under Imperfect LoS Phase Tracking
Noor Ul Ain, Lorenzo Miretti, Renato L. G. Cavalcante +1
We study the impact of imperfect line-of-sight (LoS) phase tracking on the uplink performance of cell-free massive MIMO networks. Unlike prior works that assume perfectly known or…
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…
Towards Bridging the Gap between Near and Far-Field Characterizations of the Wireless Channel
Navneet Agrawal, Ehsan Tohidi, Renato L. G. Cavalcante +1
The "near-field" propagation modeling of wireless channels is necessary to support sixth-generation (6G) technologies, such as intelligent reflecting surface (IRS), that are enable…
Two-timescale joint power control and beamforming design with applications to cell-free massive MIMO
Lorenzo Miretti, Renato L. G. Cavalcante, Sławomir Stańczak
In this study we derive novel optimal algorithms for joint power control and beamforming design in modern large-scale MIMO systems, such as those based on the cell-free massive MIM…
