Performance Evaluation of Ka- and Q-band Earth-Space Diversity Systems in Attica, Greece using the Synthetic Storm Technique

摘要

The successful migration of satellite communication systems to higher frequency bands such as Ka-and Q-band necessitates the use of accurate channel statistics and propagation models. In this paper a statistical evaluation of rain attenuation in Attica, Greece is performed using emulated data obtained through the Synthetic Storm Technique (SST). The 2-years rainfall rate dataset available at NTUA for two locations is used as input to the SST to obtain rain attenuation time series. Both overall as well as diurnal, long-term statistical analysis is performed; additionally, site diversity scenarios are evaluated, investigating the impact of employing an attenuation threshold with hysteresis when switching between the ground stations. Finally, outage capacity statistics are investigated considering both conventional Single Input Single Output (SISO) and Single Input Multiple Output (SIMO) scenarios.
