description |
Ku-band have a larger attenuation during heavy rain in the equatorial region.
Despite that, Ku-band has been identified as a frequency band in
high-throughput satellite systems (HTS) for broadband satellite
communication. The available rain fade prediction models are still not able
to accurately predict rain attenuation in the equatorial region. The models
depend on the specific attenuation parameters produced based on the
international telecommunication union radiocommunication sector (ITU-R)
instead of the measured value. Direct measurement of specific attenuation is
more accurate but difficult to obtain because the correlation of rainfall rate
and satellite signal loss due to rain must be obtained simultaneously.
This paper aims to derive new specific attenuation frequency-dependent
coefficients for Ku-band using the semi-empirical method. The Malaysia
East Asia Satellite 3 (MEASAT-3) satellite data was collected using a 13 m
antenna located at Cyberjaya, Selangor while the rainfall data was collected
by the nearby hydrological station. The specific attenuation was obtained
from correlations of the direct measurement of rain attenuation and rainfall
rate. The new frequency-dependent coefficients for Ku-band specific
attenuation values are k = 4.6690 and α = 0.1941. The newly acquired
specific attenuation coefficients have improved the rain attenuation model
prediction for the equatorial region. |
