Beam-hopping-based design of the next generation high throughput satellite communication system

Abstract

Beam-hopping technology is regarded as a fundamental component of the new generation of high-throughput satellite systems since it offers a foundation for adaptable resource allocation and effective use.A top-down feasibility and technical foundation was provided for the design of a new generation of high-throughput satellite communication system based on beam hopping, with the aim of service-driven, efficient utilization of resources and on-demand coverage of hot spots area. This was achieved from the aspects of system architecture, communication system, working mechanism, resource allocation method and beam-hopping pattern design, user access strategy, air interface protocol design, and system workflow.Lastly, it satisfies the need for a space-based backbone network with high dependability and enormous transmission capacity, as well as the criteria for a flexible and mobile information service for the space-earth integration network.
