In tropical regions, satellite communication links at Ku-band frequencies face excess up- and downlink paths loss due to rainfall. The uplink rain attenuation causes a decrease in the signal level received at the satellite receiver, which leads to a decrease of the satellite transmitter power. This signal level is...
