摘要
本文在单反射几何模型的基础上 ,提出了用于预测平流层通信信道功率延时扩展和空间能量分布的信道传播模型 .一个用于确定空间中不同单反射路径存在概率的地面多建筑阻挡模型在文中被提出 ,同时给出了确定此概率的计算方法 .在所提模型的基础上本文最后给出了一个平流层信道多径分量时空联合分布的典型结果 .
Referring to the geometrically based single bounce (GBSB) model,a new geo-propagation model is proposed to predict the delay spread as well as the direction-of-arrival of multipath components in channels for high altitude platform station (HAPS) communications.Furthermore,an approach to calculate the probability of existence of single bounce paths caused by building blockages is given.By using the model,numerical simulation gives the power delay profile and the joint time-angle spread of the HAPS channels.
