Optimization of return link carrier planning for brandband GEO satellite communications

To enhance resource utilization in GEO satellite return links, this paper proposes a novel dynamic carrier configuration optimization algorithm (CCOA) to address the carrier planning and allocation problem in Ka/Ku-band broadband satellite networks. Under throughput and outage probability constraints, CCOA dynamically adjusts carrier allocation based on rain attenuation levels by grouping user traffic, adapting to the time-varying channel conditions. SNS3 simulation results demonstrate a 9% reduction in total bandwidth occupancy and a significant decrease in packet loss rate under rain attenuation.
