| Abstract: | Based upon the EXCELL rain cell model,a new prediction model of rain attenuation for the terrestrial line-of-sight systems is proposed,where a new path adjustment factor is developed and the parameters of path adjustment factor is regressed based on the experimental data in ITU-R database.The comparison between ITU-R model and the models developed in recent years shows that the new model has better agreement with the experimental data than other models. |
