The paper proposes a novel power and bandwidth allocation mechanism for a multibeam satellite system in Ka-band or above. At such high frequency bands, rain attenuation severely impacts the performance and the use of PIMT techniques, such as the ACM technique foreseen in the DVB-S2 standard, is crucial. The proposed resource allocation mechanism is based on the observation that it would be more efficient not to waste satellite resources to serve users that are experiencing too high rain attenuation and re-distribute them to other users in better channel conditions. Based on a proper modeling of the multibeam coverage and rain distribution, and assuming the use of ACM techniques, the performance of the proposed algorithm have been shown through simulation results. The results proves its effectiveness in terms of reduced gap between traffic demand and supplied throughputs.
