Adaptive Resource Coordination in Dynamic Multi-Satellite ICAN Systems

Develop adaptive joint resource-allocation schemes for dynamic multi-satellite broadband LEO integrated communication and navigation systems that respond in real time to changing link conditions and diverse communication and navigation service requirements while maintaining an appropriate balance among competing service demands.

Background

Broadband LEO integrated communication and navigation systems must share limited resources between communication and navigation services. Multi-satellite asynchronous transmission further complicates subcarrier and power coordination, mutual communication-navigation interference mitigation, and inter-satellite interference management.

Although existing resource-allocation methods jointly allocate subcarriers and power for particular system configurations and optimization objectives, the paper states that their adaptability to dynamic link conditions and heterogeneous service requirements is limited. The unresolved problem is to achieve adaptive, real-time coordination across dynamic multi-satellite scenarios while balancing competing service demands.

However, such resource allocation methods are typically designed for specific system configurations and optimization objectives, and their adaptability to dynamic link conditions and diverse communication and navigation service requirements remains limited.
