Determination of Ku-band specific attenuation parameters based on measurements in the tropics
Attenuation due to rain is a critical constraint in the design of Earth-space links especially at frequencies higher than 10 GHz. Rain attenuation prediction models proposed by ITU-R were reported to offer good estimation for temperate regions but a number of studies reveal that it severely unde...

| Summary: | Attenuation due to rain is a critical constraint in the
design of Earth-space links especially at frequencies higher than
10 GHz. Rain attenuation prediction models proposed by ITU-R
were reported to offer good estimation for temperate regions but
a number of studies reveal that it severely underestimates the
concerned signal in the tropics. The study attempted to derive
new applicable specific attenuation coefficients using one-year 11
GHz satellite beacon data and rainfall rate measurements in
Malaysia. The acquired outcomes are incorporated in the ITU-R
procedure to assess their suitability and significance |
