在理论研究的基础上，提出一种新的卫星信道模型。模型按照卫星直视信号受遮挡的程度不同，将陆地卫星移动通信信道质量的变化描述为三个不同的状态。同时考虑了卫星对接收机仰角不同对信道参数的影响，使得对信道特性的描述更加直观、合理。
Based on the theoretical research, a new satellite channel model is proposed. The model describes the changes in terrestrial satellite mobile communication channel quality as three different states, depending on the extent to which the satellite’s direct-view signal is occluded. At the same time, the influence of different satellites on receiver parameters on channel parameters is considered, which makes the description of channel characteristics more intuitive and reasonable.
