About this Research Topic
Space Information Networks (SIN) are based on space platforms, and provide communication, navigation and remote sensing services. As important parts of the national infrastructure and global hot research areas, SIN may expand human activities by acquiring, processing and transmitting a wide range of information, and through fusion with terrestrial networks. However, the development of SIN is likely restricted by spectrum and orbit resources.
As a vital development aspect of Space Information Networks (SIN), Space-Aerial-Terrestrial (SAT) networks are designed to provide roaming services for users or devices in various scenarios, including land, aerial and marine areas. Simultaneously, SAT networks are expected to be one of the vital supports for intelligent transportation systems, global environment surveillance and space information networks. However, SAT networks are confronting enormous challenges caused by various peculiar space physical characteristics and technology gaps, such as dynamic space topology networks, compatibility with terrestrial 5G/6G technologies, service integration involving communication, navigation and remote sensing, and the requirements of lower cost and green communications.
This Research Topic focuses on the novel architectures, sustainable integration models, advanced signal processing, and performance optimization for SAT networks, including, but not limited to, the following topics：
• Integrated or hybrid architectures for SAT networks
• Innovative signal process for satellite communications
• Role of satellite in 5G/6G service scenarios
• Network function Virtualization (NFV) and Software Defined Networking (SDN) applied in SAT networks
• Interference management for SAT networks
• Massive access schemes for mobile users with large scale mobility
• Spectrum sensing for self-organization networks
• Performance optimization of SAT networks
• Deep learning/ machine learning for integrated or hybrid network Frameworks.
