Semantic-Aware Task Clustering for Federated Cooperative Multi-Task Semantic Communication
Ahmad Halimi Razlighi, Pallavi Dhingra, Edgar Beck +2
Task-oriented semantic communication (SemCom) prioritizes task execution over accurate symbol reconstruction and is well-suited to emerging intelligent applications. Cooperative mu…
6G Resilience -- White Paper
Hirley Alves, Nurul H. Mahmood, Onel L. A. López +36
6G must be designed to withstand, adapt to, and evolve amid prolonged, complex disruptions. Mobile networks' shift from efficiency-first to sustainability-aware has motivated this…
Sparse Incremental Aggregation in Satellite Federated Learning
Nasrin Razmi, Sourav Mukherjee, Bho Matthiesen +2
This paper studies Federated Learning (FL) in low Earth orbit (LEO) satellite constellations, where satellites are connected via intra-orbit inter-satellite links (ISLs) to their n…
Robust Precoding via Characteristic Functions for VSAT to Multi-Satellite Uplink Transmission
Maik Röper, Bho Matthiesen, Dirk Wübben +2
The uplink from a very small aperture terminal (VSAT) towards multiple satellites is considered, in this paper. VSATs can be equipped with multiple antennas, allowing parallel tran…
Scheduling for Ground-Assisted Federated Learning in LEO Satellite Constellations
Nasrin Razmi, Bho Matthiesen, Armin Dekorsy +1
Distributed training of machine learning models directly on satellites in low Earth orbit (LEO) is considered. Based on a federated learning (FL) algorithm specifically targeted at…
Beamspace MIMO for Satellite Swarms
Maik Röper, Bho Matthiesen, Dirk Wübben +2
Systems of small distributed satellites in low Earth orbit (LEO) transmitting cooperatively to a multiple antenna ground station (GS) are investigated. These satellite swarms have…
On-Board Federated Learning for Dense LEO Constellations
Nasrin Razmi, Bho Matthiesen, Armin Dekorsy +1
Mega-constellations of small-size Low Earth Orbit (LEO) satellites are currently planned and deployed by various private and public entities. While global connectivity is the main…
Ground-Assisted Federated Learning in LEO Satellite Constellations
Nasrin Razmi, Bho Matthiesen, Armin Dekorsy +1
In Low Earth Orbit (LEO) mega constellations, there are relevant use cases, such as inference based on satellite imaging, in which a large number of satellites collaboratively trai…
Reconfigurable Intelligent Surfaces: A Signal Processing Perspective With Wireless Applications
Emil Björnson, Henk Wymeersch, Bho Matthiesen +3
Antenna array technology enables directional transmission and reception of wireless signals, for communications, localization, and sensing purposes. The signal processing algorithm…
