• W20206380 abstract "Interference management and interference cancellation are addressed in the satellite communication (SATCOM) system. We first introduce the two options for a multibeam payload: flexible (FLEX) where allocation is fully flexible in the frequency domain, and conventional on which beamforming (BF) is applied. Further, two optimization problems are proposed, P1: spectral mask vector design and power allocation in the FLEX SATCOM system by interference management, and P2: BF weighting vector design and power allocation in the BF SATCOM system by interference cancellation. Specifically, we provide a resource allocation algorithm for each system. The performance of the resource allocation algorithm is evaluated with asymmetrical traffic distribution models. The numerical results show that, by using interference cancellation, BF system with full frequency reuse provides the best performance. For the FLEX system, the bandwidth can be utilized more efficiently with larger frequency reuse factor and smaller bandwidth granularity.KeywordsMultibeam satelliteresource allocationinterference managementinterference cancellation" @default.
