| Summary: | Rainfall can cause severe degradation to the operation of microwave links
working with frequencies above 10 GHz. Many studies have investigated this
problem, and one of the factors that attract the attention of researcher is rain
fade slope which is the rate of change of rain attenuation. The focus of this
study is on rain fade slope for terrestrial links and it is based on measurement
conducted in Malaysia. This paper investigates the characteristics of the
measured rain fade slope distribution for various attenuation levels. Then, the
ITU-R model for rain fade slope is compared with the corresponding
statistics obtained from the measured data. Significant discrepancies have
been observed since the ITU-R prediction model does not fit the measured
fade slope distribution for many attenuation levels. It is recommended to
modify the expression of the standard deviation in the ITU-R model when
implemented in tropical regions. |
