摘　　要：通过在Matlab/Simulink软件平台上对天线、信号调制和自由空间传播损耗等卫星通信链路模块进行设计封装,搭建出IDR和SCPC的卫星通信链路。IDR卫星仿真链路采用时分复用的方式对32路TDM信号进行仿真,信道编码采用3/4码率的前向纠错码;SCPC卫星仿真链路采用伯努利二进制信号生成器产生数据流,采用QPSK调制方式。卫星通信仿真系统可通过改变相关模块的参数设置满足不同的需求,提供分析评估模型,预测在不同情况下卫星通信系统的性能,方便理论知识的学习和研究,为实际工程设计提供依据和参考作用。The IDR and SCPC satellite communication links were constructed by packaging the antenna,signal modulation and free-space propagation loss modules on the Matlab/Simulink software platform.The SCPC satellite emulation link uses a Bernoulli binary signal generator to generate the data stream,using QPSK modulation.The satellite communication simulation system can meet different requirements by changing the parameter settings of the relevant modules,providing analysis and evaluation models to predict the performance of satellite communication systems under different circumstances,facilitating the learning and re search of theoretical knowledge,and providing a basis and reference role for practical engineering design.
