| 摘要: |
| 陆地移动卫星信道通常用全阴影模型和部分阴影模型进行分析。本文利用全阴影模型的研究结论，就实际陆地移动卫星信道部分阴影模型的仿真问题，拟合了模型参数与卫星仰角之间的关系。通过统计特性的数值计算，验证了部分阴影模型与全阴影模型的一致性。 |

| The Channel models for Land Mobile Satellite in Shadowing Environment |
|
| () |
| Abstract: |
| We can model the channels of land mobile satellite (LMS) in shadowing environment by consideration of complete shadowing effect and partial shadowing effect. The complete shadowing model has been investigated by some of published papers. These research results have been used to design the partial shadow model for simulating the same channel of LMS. The author fits the curves between the model parameters and satellite elevations. The consistency has been testified by the numerical results of statistical parameters both complete and partial shadowing models. |
