A composite channel model, which combines ionospheric scintillation fading and terrestrial multipath effects, has been developed for the new satellite communications system, the Mobile User Objective System MUOS. We numerically solve the composite model and compute an effective decorrelation time and coherence bandwidth for the composite channel. We find that, under typical conditions, the effective channel decorrelation time and coherence bandwidth can be different from the ionospheric or terrestrial channel parameters.
