Interfade and inter-event interval: A time-based classification and modelling

The fade dynamics is a major subject when designing the so-called Fade Mitigation Techniques (FMTs), which allow to compensate for the in excess channel attenuation, ensuring the proper link availability and costumers' quality-of-service (QoS). The interfade duration is generally defined as the time lapse between two consecutive fade-events; it enables an operator to evaluate the system capacity to recover before the following fade-event and assists the design of FMTs. However, not only it has been poorly studied in the past, as it would also be interesting to establish a relationship between interfade duration and its underlying physical phenomena and, at the same time, extract each component from the entire time lapse between consecutive fade-events, once each one should be associated different physical phenomena. In this work a time-based classification is applied in order to separate each interfade duration component and differentiate interfade duration from inter-event duration. A first approach on modelling each component is also presented and evaluated.
