[en] Precoding Scheduling Link Adaptation ; multibeam ; mobile channel
[en] This paper deals with the problem of precoding,
scheduling and link adaptation in next generation mobile interactive
multibeam satellite systems. In contrast to the fixed satellite
services, when the user terminals move across the coverage area,
additional challenges appear. Due to the time varying channel, the
gateway has only access to a delayed version of the channel state
information (CSI) which can eventually limit the overall system
performance. However, in contrast to general multiuser multipleinput-
multiple-output terrestrial systems, the CSI degradation in
multibeam mobile applications has a very limited impact for
typical fading channel and system assumptions. Under realistic
conditions, the numerical results show that precoding can offer an
attractive gain in the system throughput compared to conservative
frequency reuse allocations.
