Millimetre-wave propagation channel based on NYUSIM channel model with consideration of rain fade in tropical climates

Abstract

The impact of atmospheric attenuation on wireless communication links is much more severe and complicated in tropical regions. That is due to the extreme temperatures, intense humidity, foliage and higher precipitation rain rates. This paper investigates the propagation of mm waves at 38 GHz. Key propagation channel parameters such as the path loss, path loss exponent, Rician K-factor, root mean square, delay spread and received power have been investigated considering the rain attenuation. The NYUSIM simulator was used. The analysis results have been classified considering rain attenuation, antenna setup, link distances, antenna height and antenna gain.
