Next-generation 5G cellular networks are expected to operate on the millimeter wavelength frequencies (e.g., 28 GHz and 38 GHz) to offer broader bandwidths and higher data rates. In this frequency band, rain is a major impairment to received signal power. This work aims to improve predictions of rain attenuation for 5G wireless networks operating at 28 GHz and 38 GHz in heavy rain regions, by exploiting...
Site diversity is one of the advanced techniques that aim to mitigate propagation impairments affecting satellite communication (SatCom) systems operating above 10 GHz. In this work, we exploit two years of weather radar data collected at Johor (Malaysia) to simulate a site diversity SatCom system operating at 18.9 GHz with two links pointing to the WINDS satellite (elevation angle equal to 44°)....
This work evaluates the spatial features of the synthetic rain cell profile based on two years of real rain cells database extracted from weather radar observation located in Kluang, Johor, Malaysia. Single rain cells modeled by an analytical exponential and Gaussian profile are evaluated and investigated based on certain features of real rain cells such as maximum rain rate and root mean square rain...
This work investigates the physical structure and geometrical features of rain cells based on two years of meteorological observations collected by a radar located at Kluang, Johor, Malaysia. Raw radar data are duly processed and rain cells are identified to carry out a detailed investigation on some features of the rain cells such as the mean rain rate, the equivalent minor and major axis length...
This paper presents the application of the Lowered EXCELL model to discriminate between stratiform and convective precipitation in Kuala Lumpur, Malaysia, which is located in the equatorial region. The model generates two longterm cumulative distribution functions (CDFs) that separately account for the two different types of rain, based on the input rainfall statistics reflecting the local climatology...
