Flexible User Mapping for Radio Resource Assignment in Advanced Satellite Payloads
Tomás Ramírez, Carlos Mosquera, Nader Alagha
This work explores the flexible assignment of users to beams in order to match the non-uniform traffic demand in satellite systems, breaking the conventional cell boundaries and se…
System Design for the Event Horizon Imaging Experiment Using the PECMEO Concept
V. Kudriashov, M. Martin-Neira, I. Barat +4
The concept for space interferometry from Polar or Equatorial Circular Medium Earth Orbits (the PECMEO concept) is a promising way to acquire the image of the "shadow" of the event…
An Event Horizon Imager (EHI) Mission Concept Utilizing Medium Earth Orbit Sub-mm Interferometry
V. Kudriashov, M. Martin-Neira, F. Roelofs +17
Submillimeter interferometry has the potential to image supermassive black holes on event horizon scales, providing tests of the theory of general relativity and increasing our und…
NOMA Schemes for Multibeam Satellite Communications
Ana I. Perez-Neira, Marius Caus, Miguel Angel Vazquez +1
Non-orthogonal multiple access (NOMA) schemes are being considered in 5G new radio developments and beyond. Although seminal papers demonstrated that NOMA outperforms orthogonal ac…
Architectures and Key Technical Challenges for 5G Systems Incorporating Satellites
A. Guidotti, A. Vanelli-Coralli, M. Conti +10
Satellite Communication systems are a promising solution to extend and complement terrestrial networks in unserved or under-served areas. This aspect is reflected by recent commerc…
Pushing for higher rates and efficiency in Satcom: the different perspectives within SatNExIV
Miguel Ángel Vázquez, Ana Pérez-Neira, Carlos Mosquera +7
SatNEx IV project aims at studying medium and long term directions of satellite telecommunication systems for any of the commercial or institutional applications that can be consid…
Improving the Spectral Efficiency of Nonlinear Satellite Systems through Time-Frequency Packing and Advanced Processing
Amina Piemontese, Andrea Modenini, Giulio Colavolpe +1
We consider realistic satellite communications systems for broadband and broadcasting applications, based on frequency-division-multiplexed linear modulations, where spectral effic…
A Network-Coded Diversity Protocol for Collision Recovery in Slotted ALOHA Networks
Giuseppe Cocco, Nader Alagha, Christian Ibars +1
We propose a collision recovery scheme for symbol-synchronous slotted ALOHA (SA) based on physical layer network coding over extended Galois Fields. Information is extracted from c…
