Nettetbeam), and to generate and transmit signals to antenna elements (beam creation)[2]. As any two adjacent spot beams must use different frequencies to avoid interference, combinatorial and repeti-tive use of seven frequencies is under consideration. An example of such repetitive arrangements of seven frequen-cies is shown in Fig. 3. Nettet8. des. 2024 · Abstract: Aggressive frequency reuse in the forward link of multibeam satellite communication causes considerable inter-beam interference. It is possible to use such inter-beam interference in a beneficial way …

Nettetis employed to mitigate the inter-beam interference and scale the transmission power. Moreover, we propose a heuristic user scheduling algorithm to determine the links between satellites and GUs. Subsequently, we propound two implementation schemes: a separate scheme and a joint scheme. Simulation results show that the JHU scheme outperforms ... NettetPerson as author : Pontier, L.
