Fade Dynamics on Earth-Space Paths at Ku-Band in Fukuoka, Japan Fade-Slope Evaluation, Comparison, and Model

Using an efficient approach for data analysis, we discuss the evaluation of the fade slope as a function of sampling rate. From our analysis, we found that the standard deviation of the fade slope, as a function of attenuation, has a maximum and does not match the model recommended in ITU-R P.1623. Based on this observation, an improved fade-slope model is proposed.
