摘 要：The design of reliable SatCom systems becomes critical, especially in the Q/V and W bands in which atmospheric fades are so strong that the traditional planning approach based on fixed power margins is no longer effective either because of technological constraints and/or extremely high costs. In this scenario, smart solutions known as Fade Mitigation Techniques (FMTs) are mandatory to optimize the system or to guarantee high-availability of the system even under extreme atmospheric conditions. This, in turn, triggers the need of more complex models not only aiming at accurately and reliably predicting the attenuation caused by all atmospheric constituents (gases, clouds and hydrometeors), but also able to simulate complex systems implementing FMTs and to estimate their performance in enhancing the delivered Quality of Service (QoS). This research activity focused on the performance evaluation of SatCom systems operating in the Q/V and W bands.
