摘要
文章首先简要介绍了DVB-RCS(回传信道通过卫星的数字视频广播)卫星互动网络结构。在DVB-RCS网络中,作为采用MF-TDMA(多频时分多址)技术的卫星网络系统,由于支持更多的终端与主站之间的通信,终端在系统中的同步问题就变得更加的重要。文中主要研究了捕获突发和完成终端在网络中的时钟同步、载波同步和突发同步,在对系统终端同步研究基础上,文中给出了一个RCST的同步流程。
This paper first tells of the structure of DVB-RCS satellite interactive network. In the DVB-RCS network, the MF-TDMA-based satellite network system supports more communications between the terminals and mainstations and thus the synchronization of the terminals in the system become more important. This paper focuses on the capture of the burst and the timing, carrier and burst synchronizations of the terminals in the network. And based on the study of system terminal synchronization, this paper gives a RCST synchronization flowchart.
