Preliminary analysis of ITU-R rain attenuation time series synthesizers in equatorial Kuala Lumpur

Abstract

This contribution investigates the performance of the model currently recommended by ITU-R for the synthesis of rain attenuation time series (recommendation P.1853). The Synthetic Storm Technique (SST) is used to generate reference rain attenuation time series from one year of 1-minute integrated rain rate samples collected by means of a disdrometer located at Kuala Lumpur, Malaysia. First-and second-order statistics calculated from the reference and synthetic rain attenuation time series are compared. In addition, fade duration statistics as estimated by the prediction model in ITU-R recommendation P.1623 are included in the comparison. Preliminary results suggest an acceptable performance of the time series synthesizer included by ITU-R in recommendation P.1853. However, further investigations on the input parameters to such model (e.g. higher operating frequencies, lower elevation angles and dynamic parameterβ) are necessary to confirm its applicability in this specific equatorial region.
