Some fundamental considerations about the design of broadband multimedia communication satellite system in China

摘要

China Academy of Space Technology (CAST) is currently making its first attempt to design the Chinese Broadband Multimedia Satellite Communication System. This satellite has many new features and this paper presents some fundamental ideas about its design. The general architecture and protocol stack of the system are outlined first. Some unique characters, such as service classes, beam coverage, frequency planning and multiple access, link budget analysis and radio resource management, are illustrated. It also describes the space and ground segment.
