Abstract EN
We propose a multicast scheme for multibeam satellitesystems exploiting both the multiuser and spatial diversity inherentin this type of systems while taking into account realistic physicaldistributions of User Terminals (UTs) over the coverage.
Our proposedscheme makes use of the well-known Adaptive Coding and Modulation(ACM) feature in Digital Video Broadcasting over Satellite, 2nd Generation(DVB-S2) and Extension (DVB-S2X) standards but also incorporates aset of innovative features.
First, multilink reception, that is, receiversthat can syntonize different frequencies and/or polarizations, togetherwith Network Coding (NC) is used to enable decoding of signals fromadjacent beams (spatial diversity).
Second, efficient and fair allocationof resources is achieved through Proportionally Fair Multicast (PFM)scheduling.
Our results, obtained over realistic nonuniform UTs distributions,show average system multicast throughput gains up to 88% with regardto state-of-the-art multicast schemes.
Furthermore, a complete cross-layerarchitecture is proposed, fully compliant with the standard providingQuality of Service (QoS) guarantees.
