Learning-Assisted Rain Attenuation Prediction Models
Applied Sciences, 2020 Rain attenuation becomes significant to degrade the earth-space or terrestrial radio link’s signal-to-noise ratio (SNR). So, to maintain the desired SNR level, with the help of fade mitigation techniques (FMTs), it needs to control transmitted signals ...

On Frequency Scaling of Rain Attenuation
2022 3rd URSI Atlantic and Asia Pacific Radio Science Meeting (AT-AP-RASC), 2022 In our paper we deal with the generalized method of frequency scaling. From the attenuation known at one frequency, we determine the rain rate by the inverse procedure of any rain attenuation prediction model, which we then use to estimate the rain attenuation on another frequency. We compare the results on one hand with exact values, on the other hand
