Abstract

A statistical analysis is made from the measured distribution of fade slope of rain attenuation. The experiment has been performed in Qingdao, while the signal of the beacon is from the ChinaStar-1 satellite at the frequency of 12.5GHz. The distribution of conditional probability density of fade slope shows that the positive and negative slopes are distributed symmetrically. Based on the experimental data and the ITU-R model, an improved mode of the fade slope prediction is proposed The comparison with the ITU-R model shows that the improved model obtains better performance.
