A New Method for the Prediction of Outage Probability of LOS Terrestrial Links Operating Above 10 GHz

In this letter, a new method for the prediction of outage probability due to rain attenuation for line-of-sight (LOS) terrestrial links operating above 10 GHz is presented. Assuming that rain attenuation and rain rate follow the inverse Gaussian (IG) distribution and by employing a spatial structure of the specific rain attenuation, we propose an analytical method for the calculation of the IG statistical parameters of rain attenuation in terms of the IG rain rate statistical parameters. The proposed model is validated with experimental data included in the database of the Study Group 3 (DBSG3) of the International Telecommunication Union (ITU), and it is also compared to last version of ITU-R. P.530-14 rain attenuation prediction model for terrestrial links. The results are very encouraging since the overall performance of the new model is better compared to the ITU-R P. 530-14 one.
