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…
Learning Model-Free Robust Precoding for Cooperative Multibeam Satellite Communications
Steffen Gracla, Alea Schröder, Maik Röper +3
Direct Low Earth Orbit satellite-to-handheld links are expected to be part of a new era in satellite communications. Space-Division Multiple Access precoding is a technique that re…
Energy and Bandwidth Efficiency of Event-Based Communication
Christopher Willuweit, Carsten Bockelmann, Armin Dekorsy
Wireless sensor nodes need a drastically reduced technical complexity to fit constraints of future applications. Reducing complexity often results in a degradation of energy and ba…
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…
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…
