摘要
讨论了三种卫星移动通信信道概率模型的特性 ,对其应用环境及条件进行了分析 ;并对不同地理环境的信道模型进行了计算机仿真。仿真得到的结论对估算系统的性能指标和链路分析都有一定的意义 。
The characteristics of three kinds of mobile satellite communication channel models are discussed. Both analysis of the enviroument of their applications and computer simulations for these channel models in different geographical conditions are given. The simulation results show that they are useful for the analysis of the communication performance and link quality and valuable for the prediction of impact on error rate in different modulations and error correcting code methods.
