摘要
分析低空无线信道的多径时延、多普勒效应等传输特性,利用广义平稳非相关散射模型,根据信道在停场、航行、近场、过顶4种不同场景下的特性,分别建立相应的信道模型。采用蒙特卡罗法对模型的可信性进行验证,结果表明,该信道模型能真实地反映低空无线信道的特性。
This paper analyzes the multipath delay, Doppler effect and other transmission characteristics of the low-altitude wireless channel, uses Wide Sense Stationary Uncorrelated Scattering(WSSUS) model, according to the four different scenarios of parking, en-routing, arriving and over the top models are respectively set up. Simulation experiment of this model is carried out by using the Monte Carlo(MC) method, and results show that the channel model to build a true reflection of the characteristics of low-altitude wireless channel.
