Low Earth orbit (LEO) satellite systems are expected to deliver ubiquitous broadband connectivity, but their dynamic topology and limited on-board resources challenge beam hopping (BH) scheduling and inter-satellite load balancing. This paper proposes a multi-satellite cooperative BH algorithm based on multi-agent flow...

Affine Frequency Division Multiplexing (AFDM) demonstrates significant advantages in high-mobility doubly dispersive channels. Conventional pilot-assisted channel estimation schemes necessitate high pilot power, resulting in a high pilotto-data power ratio (PDR). Reducing the pilot power makes weak multipath components...

Efficient radio resource allocation is pivotal for maximizing the service capability of Low Earth Orbit (LEO) satellite networks. However, the high mobility of satellites and the rapidly time-varying channel conditions pose significant challenges to traditional resource management schemes. Conventional optimization met...

The implementation of integrated sensing and communication (ISAC) technology in space-air cooperative systems enhances the spectral efficiency and ensures sensing and communication services for different areas. Although numerous studies have explored resource management in ISAC systems, they generally overlook the unev...
