This paper investigates the joint optimization of Flexible Inter-Satellite Link (FISL) scheduling and routing under tight coupling and mutual constraints. Traditional sequential methods break the equivalence of the original problem through decoupling, thereby leading to suboptimal performance. To overcome this limitati...

Very Low Earth Orbit (VLEO) satellites, leveraging orbital advantages, have found extensive applications in direct-to-cell (D2C) communication, high-resolution optical and radar remote sensing. The intersatellite data relay system (IDRS) can offer wide-area coverage and flexible service, promising to provide round-the-...

LEO satellites play a critical role in non-terrestrial networks (NTNs), where beam hopping (BH), enabled by phased-array antennas and flexible time-frequency division multiplexing (TFDM), enhances payload utilization. However, existing BH studies for spectrum-sharing LEO–GEO systems often neglect the co-frequency inter...

A probabilistic graphical computing paradigm based on memristors is reported, which not only unifies the framework of Bayesian inference-based baseband signal processing algorithms, but also achieves a substantial improvement in energy efficiency via memristor-based in-memory computing.
