Abstract :
Rain attenuation is predicted in various compositions of the frequency, the elevation angle, the rain-fall rate, the percent of the time, the polarization angle, the altitude of the earth station and the latitude of the earth station by means of artificial neural network in this paper. The rain attenuation prediction model of millimeter waves based on an artificial neural network is proposed for the first time, and the predicted results are compared with the CCIR recommendation model. The results show that the artificial neural network can obtain the nonlinear relation of the rain attenuation and the other factors that affect millimeter wave propagation attenuation and improve the accuracy of rain attenuation prediction with a 1.3 dB increase on average. It is a useful approach to construct the rain attenuation prediction model of millimeter wave with artificial neural network
