The Design And Implementation Of The Satellite Communication Link And Co-simulation Platform

The satellite communication system is widely used in communication, transportation, military and other fields, and plays an important role. However, There are various kinds of noise and interference in the satellite communication link, jamming analysis plays an important role in improving the quality of link communication. How to ensure the safety and smoothness of the information transmission, and to prevent the interference and destruction of information has become an urgent problem to be solved.Today, with the rapid development of computer technology, simulation technology with its high performance, low cost, low risk, as well as a short period of research, and has gradually become an important research tool in the fields of research. Therefore, this paper focus on the design of satellite communication link and the co-simulation platform, and what we have achieved is shown as follow.1.Analyzes the current the simulation technology of satellite communication,and gives a detailed description of the simulation tools of satellite communication.the basic theory of satellite communication link design is introduced in this paper, which includes satellite communication system composition, basic transmission work process, the interference analysis in the link and the communication performance analysis for the transponder in communication satellite. Moreover, the simulation parameters of the link is also preseted.2.Based on SystemVue software,the satellite communication link is designed and implemented. Using ADS software to optimize the design of low noise amplifier,focus on the anti-jamming performance for the low noise amplifier of the front end of the transponder in communication satellite. The hardware-in-the-loop simulation technology for the low noise amplifier is introduced,the simulation model of low noise amplifier is replaced by the hardware material, in order to build a complete hardware-in-the-loop simulation testing platform the simulation system and hardware in the loop simulation are combined.3.The co-simulation platform interface which can set up parameters, control simulation operation and show the testing results is designed and implemented with the combination of Matlab and SystemVue. After plenty of experiments was executed on the simulation platform, the comparison between the expected results and actual results is given, the test results show that the proposed method is feasible and can provide a reference for practical applications.
