Abstract
The limited onboard beam resources bring great challenges to low earth orbit (LEO) satellite communication systems. In addition, there are lots of difficulties in satisfying the nonuniform traffic requirements. At present, multibeam satellite systems have the ability to solve the problem through utilizing beam hopping (BH) technology, which increases the system throughput by effectively scheduling beam resources. This paper proposes a BH algorithm based on multi-objective optimization, which takes into account metrics including traffic distribution, frequency multiplexing distance, time slot allocation and so on when designing BH patterns. Simulation results illustrate that the proposed algorithm performs well in throughput and average delay.
