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.
