摘要
An effective procedure for generating m equal-power log-normal scintillation sequences with any desired cross-correlation coefficient is presented. The method is focused on a multichannel generalization of the autoregressive variate generation method in order to satisfy Taylor's hypothesis of frozen turbulence. Then the effect of the turbulent kinetic energy dissipation rate, epsilon, is included in the model, breaking the uniformity of the frozen-in hypothesis and obtaining a highly realistic behavior in the generated sequences when realistic scenarios are considered in which turbulence-induced fading may be correlated.
