Asynchronous Cell-Free Wireless Networks
Hossein Maleki, Angel Lozano, Hamid Jafarkhani
This paper introduces intentional symbol-level asynchronicity as an interference-management mechanism for the uplink of cell-free networks. Rather than treating timing offsets as i…
Pilot-to-Data Power Ratio in RIS-Assisted Multiantenna Communication
Masoud Sadeghian, Angel Lozano, Gabor Fodor
The optimization of the \gls{pdpr} is a recourse that helps wireless systems to acquire channel state information while minimizing the pilot overhead. While the optimization of the…
A Reinforcement Learning Approach for Wildfire Tracking with UAV Swarms
Carles Diaz-Vilor, Angel Lozano, Hamid Jafarkhani
Suitably equipped with cameras and sensors, uncrewed aerial vehicles (UAVs) can be instrumental for wildfire prediction, tracking, and monitoring, provided that uninterrupted conne…
Spatially Consistent Air-to-Ground Channel Modeling via Generative Neural Networks
Amedeo Giuliani, Rasoul Nikbakht, Giovanni Geraci +3
This article proposes a generative neural network architecture for spatially consistent air-to-ground channel modeling. The approach considers the trajectories of uncrewed aerial v…
Spectral vs Energy Efficiency in 6G: Impact of the Receiver Front-End
Angel Lozano, Sundeep Rangan
This article puts the spotlight on the receiver front-end (RFE), an integral part of any wireless device that information theory typically idealizes into a mere addition of noise.…
Wide-Aperture MIMO via Reflection off a Smooth Surface
Andrea Pizzo, Angel Lozano, Sundeep Rangan +1
This paper provides a deterministic channel model for a scenario where wireless connectivity is established through a reflection off a smooth planar surface of an infinite extent.…
25 Years of Signal Processing Advances for Multiantenna Communications
Emil Björnson, Yonina C. Eldar, Erik G. Larsson +2
Wireless communication technology has progressed dramatically over the past 25 years, in terms of societal adoption as well as technical sophistication. In 1998, mobile phones were…
