摘　　要：SIMULINK是一个进行动态系统建模和仿真分析的软件包,支持连续、离散以及两者混合的线性及非线性系统,其最大特点是可在仿真过程中改变感兴趣的参数,实时观察系统行为的变化。文中利用MATLAB的SIMULINK平台构建了卫星通信系统模型,利用该模型仿真分析,可得到从调制、加噪声、到解调和滤波等各个环节的的卫星通信系统的星座图、眼图和频谱图及其相关的频域技术数据,为卫星通信系统的研究提供了一个较好的软件平台。SIMULINK is a dynamic system modeling and simulation analysis software package,which supports the continuous,discrete,and both-mixed linear and nonlinear system,and its most important feature is that the parameters of interest could be changed in the simulation process and the system behavior changes observed in real time.The simulation model of the satellite communication system is built up by using this toolbox and the other tool boxes based on MATLAB/SIMULINK.With the simulation model,the constellation,eye pattern,spectrum graph and related spectral technical data of satellite communication system could be obtained from signal modulation,adding noise,demodulation and filtering,thus to provide a fairly good software platform for the design of satellite communication system.
