[en] As compared to terrestrial systems, the design of
Satellite Communication (SatCom) systems require a different
approach due to differences in terms of wave propagation,
operating frequency, antenna structures, interfering sources, limitations
of onboard processing, power limitations and transceiver
impairments. In this regard, this letter aims to identify and
discuss important modeling and design aspects of the next
generation High Throughput Satellite (HTS) systems. First,
communication models of HTSs including the ones for multibeam
and multicarrier satellites, multiple antenna techniques, and for
SatCom payloads and antennas are highlighted and discussed.
Subsequently, various design aspects of SatCom transceivers
including impairments related to the transceiver, payload and
channel, and traffic-based coverage adaptation are presented.
Finally, some open topics for the design of next generation HTSs
are identified and discussed.
