Abstract
The fade dynamic is used in order to characterize the satellite propagation channel conditions. Two parameters (among others) allow the assessment of the fade dynamics: the fade and the inter-fade durations. When testing fade duration models they do not behave as good as it is desirable. In the case of inter-fade duration, there is not an accepted model to describe its statistical behavior. Furthermore, modeling efforts at Q-band are scarce. These are the reasons to conduct a fade and inter-fade duration modeling effort using a 3-year period of measurements from the Q-band Alphasat experiment in Madrid. To achieve that, several function combinations were tested to describe the probability of occurrence either for fade or inter-fade durations. Results show that a two log-normal combination allows describing properly both parameters, but some modifications must be made in the fade-duration case. Also, a three log-normal distribution may be used if it is required the description of inter-fade durations longer than one million seconds.
