| Abstract: | Network synchronization is a key technology of satellite communication system. Aiming at the MF-TDMh/TDM based new-generation broadband communication satellite system in China, the overall network synchronization scheme is proposed, and the frame synchronization architecture and the signal flow are designed for uplink and downlink respectively, and some key issues are discussed in detail, including timing acquisition, quick resynchronization and timing control. |
