摘要
MF-TDMA卫星通信体制组网灵活,支持综合业务接入,能够实现大小终端同网工作,并且可以针对不同的应用需求进行灵活设计,目前已成为国内外卫星应用、发展及研究的热点。从透明转发和星上处理转发2个方面介绍了目前国内外提出的一些MF-TDMA技术体制以及各自特点。结合MF-TDMA技术体制介绍了几种安全机制和抗衰落技术,以适应某些特殊应用的设计要求。
MF-TDMA satellite communication system has some special advantages. It founds the basis of constructing flexible network topology, suppers integrated service access and many kinds of terminals operating within the same network. MF-TDMA system can be designed for different applications. It is becoming the one focus of satellite communication application and development. This paper introduces some new MF-TDMA network structures at present and their characteristics from two aspects of transparent and regenerative satellite communication. Some security mechanisms and anti-fading technologies for MF-TDMA system are also investigated in order to adapt the special application scene.
