摘要：
This 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 agreement 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.
