论文摘要
由于新兴的大型星座旨在使用数百个小地球轨道（LEO）卫星为偏远地区提供无缝的连通性，因此新方法非常重要地研究了这些网络的性能。在本文中，无论卫星的确切位置如何，我们都会得出下行链路和上行分析表达式的覆盖范围概率和倾斜LEO星座的数据速率。我们的解决方案涉及两个阶段，因为我们首先将网络抽象成一个均匀分布的网络。其次，对于每个用户的纬度，我们获得了一个新的参数，有效数量的卫星，以补偿实际和统一星座之间的性能不匹配。除了精确推导网络性能指标外，本研究还提供了选择星座参数的见解，例如卫星，高度和倾斜角总数。
As emerging massive constellations are intended to provide seamless connectivity for remote areas using hundreds of small low Earth orbit (LEO) satellites, new methodologies have great importance to study the performance of these networks. In this paper, we derive both downlink and uplink analytical expressions for coverage probability and data rate of an inclined LEO constellation under general fading, regardless of exact satellites' positions. Our solution involves two phases as we, first, abstract the network into a uniformly distributed network. Secondly, we obtain a new parameter, effective number of satellites, for every user's latitude which compensates for the performance mismatch between the actual and uniform constellations. In addition to exact derivation of the network performance metrics, this study provides insight into selecting the constellation parameters, e.g., the total number of satellites, altitude, and inclination angle.
