Assessment of X-band earth-satellite link rain attenuation prediction in Malaysia

Predicted rain fade values for an Earth-satellite link operating at X-band frequency had been generated using the latest ITU-R Recommendation, P618-11. Rain fade values for the very same link were also estimated using the "radar-derived attenuation" technique. The radar technique inv...
