| contents | Satellite communication systems are shifting to higher frequency bands (Ka, Q/V, W) to support more data-intensive services and alleviate spectral congestion. However, the use of Extremely High Frequencies, typically above 20 GHz, causes significant tropospheric impairments, such as rain attenuation, which can causes system outages.
To mitigate these effects, Smart Gateway Diversity (SGD) has emerged as a promising method for maximizing feeder link availability through an adaptive site diversity scheme. However, implementing such technique requires a decision-making policy to dynamically select the optimal set of gateways and prevent outages.
This paper introduces AIRIS2, a deep learning algorithm that anticipates short-term rain events from rain attenuation measurement to enable efficient gateway switching. The approach is validated from five years of measured time series collected at Ka and Q/V bands at various sites and climatic conditions. |
