Intelligent Weather Systems with Fuzzy Logic Controller for Satellite Networks

— Weather attenuations can have a distorting effect on signal fidelity above 10 GHz that lead to excessive digital transmission error. This loss of signal is commonly referred to as signal attenuation. Signal attenuation impacts QoS in wireless and satellite networks. An intelligent decision support system is therefore necessary for service providers by accurately calculating rain, gaseous, cloud, fog, and scintillation attenuations using predicted signal-weather correlated database in collaboration with ITU-R propagation models combined with gateway, and ground terminal characteristics. The effect becomes a key feature in adjusting and improving satellite signal power, modulation and coding schemes, monitored and controlled altogether by a powerful and efficient intelligent-based attenuation countermeasure system. A three dimensional relationship is proposed among these attenuations with respect to propagation angle and rainfall rate [1]-[9]. The result pilots an enhanced back propa...
