Throughput Requirements for RAN Functional Splits in 3D-Networks

MohammadAmin Vakilifard, Tim Düe, Mohammad Rihan +4

The rapid growth of non-terrestrial communication necessitates its integration with existing terrestrial networks, as highlighted in 3GPP Releases 16 and 17. This paper analyses th…

Flexible Robust Beamforming for Multibeam Satellite Downlink using Reinforcement Learning

Alea Schröder, Steffen Gracla, Maik Röper +3

Low Earth Orbit (LEO) satellite-to-handheld connections herald a new era in satellite communications. Space-Division Multiple Access (SDMA) precoding is a method that mitigates int…

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…

A Comparison between RSMA, SDMA, and OMA in Multibeam LEO Satellite Systems

Alea Schröder, Maik Röper, Dirk Wübben +3

Low Earth orbit (LEO) satellite systems enable close to global coverage and are therefore expected to become important pillars of future communication standards. However, a particu…

Distributed Downlink Precoding and Equalization in Satellite Swarms

Maik Röper, Bho Matthiesen, Dirk Wübben +2

In this paper, we propose a novel approach for downlink transmission from a satellite swarm towards a ground station (GS). These swarms have the benefit of much higher spatial sepa…

NGSO Constellation Design for Global Connectivity

Israel Leyva-Mayorga, Beatriz Soret, Bho Matthiesen +4

Non-geostationary orbit (NGSO) satellite constellations represent a cornerstone in the NewSpace paradigm and thus have become one of the hottest topics for the industry, academia,…
