这篇文章为随即和非随机的散射环境中造成的信封衰落提供了一个AR模型。它展示了至少需要一个二阶AR过程去建立一个伏在接收信封内在的阻尼正弦自动/交叉相关函数的模型。通过对模拟值的比较得到使用模型可以得到与理论值近似的值。模型基于的仿真过程被用来与JACK仿真器在随机分散事件中作比较。(his work presents an autoregressive (AR) model
for fading envelope influenced by isotropic and non-isotropic
scattering environments. It is shown that at least a second order
AR process is required to model the damped sinusoidal auto/cross
correlation function inherent in the complex received envelope.
The comparison of statistics of the simulation trace obtained
using the model shows good agreemeqt with the theoretical
values. The model based simulation procedure is compared to
the Jake s simulator for isotropic scattering case and is shown
to exhibit an order of magnitude smaller time complexity. )
