      Satellite Precoding is a promising technique to meet the target data rates of the future high throughput satellite systems and the costs per bit as required by 5G applications and networks, but it requires strict synchronization ...
    • NOMA-enabled multi-beam satellite systems: Joint optimization to overcome offered-requested data mismatches 

      Wang, Anyue; Lei, Lei; Lagunas Targarona, Eva; Pérez Neira, Ana Isabel; Chatzinotas, Symeon; Ottersten, Björn (Institute of Electrical and Electronics Engineers (IEEE), 2021-01)
      Article
      Open Access
      Non-Orthogonal Multiple Access (NOMA) has the potentials to improve the performance of multi-beam satellite systems. The performance optimization in satellite-NOMA systems can be different from that in terrestrial-NOMA ...
    • Precoding in multibeam satellite communications: present and future challenges 

      Vazquez, Miguel Angel; Pérez Neira, Ana Isabel; Christopoulos, Dimitrios; Chatzinotas, Symeon; Ottersten, Björn; Arapoglou, Pantelis-Daniel; Ginesi, Alberto; Tarocco, Giorgio (2016-12-01)
      Article
      Open Access
      Whenever multibeam satellite systems target very aggressive frequency reuse in their coverage area, inter-beam interference becomes the major obstacle for increasing the overall system throughput. As a matter of fact, users ...
