Investigation of Rain Attenuation in Equatorial Kuala Lumpur
TL;DR: In this paper, the authors analyzed the diurnal variation of rainfall rate for four time intervals and presented statistics of rain attenuation for slant-path Earth-space links estimated by means of a new model (Stratiform-Convective SST) that combines the advantages of the Dual-Layer Synthetic Storm Technique (SST) and the SC EXCELL model.
Journal ArticleDOI
Statistical and Physical Descriptions of Raindrop Size Distributions in Equatorial Malaysia from Disdrometer Observations
TL;DR: In this article, the physical characteristics of raindrop size distribution (DSD) in an equatorial heavy rain region based on three years of disdrometer observations carried out at Universiti Teknologi Malaysia's (UTM) campus in Kuala Lumpur, Malaysia.
Proceedings ArticleDOI
Impact of rain attenuation on 5G millimeter wave communication systems in equatorial Malaysia investigated through disdrometer data
TL;DR: In this paper, the empirical power law relationship between specific attenuation and rainfall intensity is derived and compared with those for Rec. ITU-R P.838-3 and Singapore results.
Journal ArticleDOI
Rain induced attenuation studies for V-band satellite communication in tropical region
TL;DR: In this article, the effects of rain fading on satellite communications at 10 GHz and above in the tropics are investigated and several potential fade mitigation techniques that can be embarked are highlighted.
