Two-year rain fade empirical measurement and statistics of earth-space link at ka-band in Malaysia

Satellite communication links at a frequency above 10 GHz experience severe attenuation due to rain, particularly in tropical regions. Reliable long-term rain fade empirical data for Ka-band satellite link in Malaysia and tropical areas are indeed limited. The main objective of this paper is to prov...
