Investigation of the Effects of Atmospheric Attenuation and Frequency on MIMO Channel Capacity

Abstract

The efficiencies of 5G channels, which are highly affected by atmospheric attenuation, are still being investigated. The effects of frequency and atmospheric attenuation parameters such as humidity, temperature, rain, and pressure were investigated in this study using the NYUSIM program. The spatial consistency mode of the NYUSIM channel simulator was turned off, and unnormalized channel capacities were calculated at 28, 45, 60, and 73 GHz frequencies. According to the research results, the rain rate was the atmospheric attenuation parameter that significantly affected MIMO channel capacity. In contrast, the humidity percentage had the slightest impact. The frequency where the channel capacity is most affected by the four determined atmospheric attenuation parameters is 60 GHz, while the frequency where it is least affected is 28 GHz. The study found that using frequencies with high atmospheric attenuation reduces communication efficiency significantly. Furthermore, rain rate has a significant impact on 5G channel performance.
