Abstract

Multibeam satellite communication systems have received widespread attentions due to their high throughput and efficient resource utilization. This paper investigates the beam scheduling and resource allocation problem in multibeam satellite communication system. By jointly considering user position and service characteristics

an optics-based initial user grouping algorithm is proposed. To enhance beam coverage performance

a minimum circle algorithm is proposed to optimally design satellite beam positions and coverage radius. Given the determined user grouping strategy

system cost function is defined and the joint beam scheduling

sub-channel allocation and power allocation problem is formulated as a system cost function minimization problem. To solve the formulated optimization problem

aggregate nodes are introduced to describe the characteristics of user groups

and a parameterized deep
