摘要
针对实际需求,给出了一种高速双通道卫星调制解调器的设计实现方法。从调制解调器总体设计架构出发,阐述了调制解调器所使用的硬件架构及软件平台,详细介绍了信道纠错编码、可变速率带宽及高速高效双通道等关键技术的设计及实现。对调制解调器性能进行了测试,结果表明在不同的速率及编码环境下,满足卫星通信的要求,减少了组网环境下通信设备数量,降低了运维成本,具有广阔的应用前景。
In view of the actual demands,a design and implementation method of a high-speed dual channel satellite modem is given. Starting from the overall design architecture of the modem,the hardware architecture and software platform used by the modem are expounded,and the design and implementation of some key technologies such as the channel error correcting code,variable rate bandwidth and high-speed and high-efficiency dual channel are introduced in detail. The properties of the modem are tested,and the results show that in different rate and coding,the modem can satisfy the requirement of satellite communication,decrease the number of communication devices in the network environment,and reduce the operation and maintenance cost,and have broad application prospects.
