| Abstract(in English) | Beam hopping system sharing transmitting resources in time enables satellites and gateways to reduce their costs for increased HTS capacity. However, the conventional beam hopping system decreases frequency efficiency if the traffic demands vary among clusters because it shares their resources only in a cluster. Therefore, this paper proposes the novel beam hopping technique which overlaps each of clusters to share transmitting resources among them. Moreover, this paper proposes optimal beam assignment algorithm using mini-batch stochastic gradient descent (SGD) to maximize system throughput considering satellite transmitting antenna pattern and traffic generated area. The effectiveness of the proposal is verified through simulation results. |
