[en] This paper designs dynamic on-board signal processing
schemes in a multiple gateway multibeam satellite system
where full frequency reuse pattern is considered among the beams
and feeds. In particular, we deploy on-board Joint Precoding,
Feed selection and Signal switching mechanism (JPFS) so that the
following advantages are realized, I) No need of Channel State
Information (CSI) exchange among the gateways and satellite,
since the performance of precoding is highly sensitive to the
quality of CSI, II) In case one gateway fails, rerouting signals
through other gateways can be applied without any extra signal
processing, III) Properly selecting on-board feed/s to serve each
user which generates maximum gain toward corresponding user,
IV) Flexibly switching the signals received from the gateways
to requested users where each user can dynamically request
traffic from any gateway, and V) Multiple user with multiple
traffic streams can be dynamically served at each beam. However,
deploying such JPFS architecture imposes high complexity to the
satellite payload. To tackle this issue, this study aims at deploying
JPFS that can provide affordable complexity at the payload. In
addition, while increasing the data demand imposes extensive
bandwidth resources requirement in the feeder link, the proposed
JPFS design works efficiently with available feeder link resources
even if the data demand increases. The proposed design is evaluated
with a close-to-real beam pattern and the latest broadband
communication standard for satellite communications.
