DVB—RCS协议研究

摘要

The DVB RCS communication systems, which are based on interaction applications, have attracted much attention recently. This paper first introduces the reference model and the protocol stack of DVB RCS systems. Then, the forward link protocol and the return link protocol are analyzed, respectively. Finally, sev- eral technical difficulties of the DVB RCS systems are described.%DVB—RCS通信系统是基于交互式应用的卫星通信系统，目前已受到业界的广泛关注。首先介绍了DVB—RCS系统的模型和协议结构，然后分别对前向信道和反向信道协议进行了分析，最后对所存在的问题进行了说明。
