Details
The problem of resource allocation in high-throughput satellite communication systems operating in geostationary orbit is addressed. The research work developed a comprehensive optimisation tool, SatDreamOpt, to optimise the use of limited satellite resources such as frequency, bandwidth, and power, while meeting the constraints of modern channelised satellite systems.
The tool provides solutions to five main optimisation problems: 1) Beam laydown plan - determines the optimal size and placement of beams, 2) User-to-beam allocation - assigns users to the appropriate beams based on their location and demands, 3) Bandwidth allocation - optimally allocates bandwidth to each user to meet requested demand, 4) Power allocation - determines the optimal transmit power level for each user to minimise interference and maximise received signal quality, 5) Channelisation - allocates sub-channel frequencies to users to minimise interference from adjacent beams.
For an exemplar satellite system, SatDreamOpt can produce end-to-end solutions for over 1000 links within 5-10 minutes. The tool can be applied in both the planning (design) phase and the operational phase to enhance efficiency and performance. The use of SatDreamOpt can lead to improved service quality, reduced interference, and optimal use of limited resources in satellite communication networks.
