Joint Optimization of Beam-Hopping Design and NOMA-Assisted Transmission for Flexible Satellite Systems
Anyue Wang, Lei Lei, Eva Lagunas +3
Next-generation satellite systems require more flexibility in resource management such that available radio resources can be dynamically allocated to meet time-varying and non-unif…
Signal Processing for High Throughput Satellite Systems: Challenges in New Interference-Limited Scenarios
Ana I. Perez-Neira, Miguel Angel Vazquez, Sina Maleki +2
The field of satellite communications is enjoying a renewed interest in the global telecom market, and very high throughput satellites (V/HTS), with their multiple spot-beams, are…
Generalized Multicast Multibeam Precoding for Satellite Communications
Vahid Joroughi, Miguel Ángel Vázquez, Ana I. Pérez-Neira
This paper deals with the problem of precoding in multibeam satellite systems. In contrast to general multiuser multiple-input-multiple-output (MIMO) cellular schemes, multibeam sa…
Precoding in Multigateway Multibeam Satellite Systems
Vahid Joroughi, Miguel Ángel Vázquez, Ana I. Pérez-Neira
This paper considers a multigateway multibeam satellite system with multiple feeds per beam. In these systems, each gateway serves a set of beams (cluster) so that the overall data…
On-Board Beam Generation for Multibeam Satellite Systems
Vahid Joroughi, Miguel Ángel Vázquez, Ana I. Pérez-Neira +1
This paper aims at designing an on-board beam generation process for multibeam satellite systems with the goal of reducing the traffic at the feeder link. Full frequency reuse amon…
Precoding in Multibeam Satellite Communications: Present and Future Challenges
Miguel Ángel Vázquez, Ana Pérez-Neira, Dimitrios Christopoulos +5
Whenever multibeam satellite systems target very aggressive frequency reuse in their coverage area, inter-beam interference becomes the major obstacle for increasing the overall sy…
