论文摘要
由于仅在瑞利距离内可用多个输入多重输出（LOS MIMO）通道的正交性，因此由于天线的有限实现间距，通信系统的覆盖范围受到限制。但是，在传输路径中具有不同介电常数的介质可能会松开天线间距的要求。考虑到对流层中云的存在，这种结论可能会在空对地面的MIMO场景中启发。为了分析在单层云的存在下的随机相位变化，我们提出并修改了一种基于真实测量数据的新云建模方法适合LOS MIMO场景。然后，基于模拟结果对通道容量进行初步分析。
Since the orthogonality of the line-of-sight multiple input multiple output (LoS MIMO) channel is only available within the Rayleigh distance, coverage of communication systems is restricted due to the finite implementation spacing of antennas. However, media with different permittivity in the transmission path are likely to loosen the requirement for antenna spacing. Such a conclusion could be enlightening in an air-to-ground LoS MIMO scenario considering the existence of clouds in the troposphere. To analyze the random phase variations in the presence of a single-layer cloud, we propose and modify a new cloud modeling method fit for LoS MIMO scene based on real-measurement data. Then, the preliminary analysis of channel capacity is conducted based on the simulation result.
