TLDR

A method of predicting scintillation fading occurring on Earth-space paths is proposed that is based on the data obtained from a low-elevation 14/11 GHz wave propagation experiment at Yamaguchi, Japan. This model includes parameters representing meteorological conditions that have not been covered in existing models and can be applied to broad regions with varying climates. The prediction accuracy of the method is evaluated using experimental data collected at four sites in the western part of Japan, as well as data reported thus far on a worldwide basis. Although data used for evaluation are limited, the model shows good prediction accuracy for frequencies from 7 to 14 GHz and elevation angles from 4 degrees to 30 degrees . >read more

Optimal transmission scheduling over a fading channel with energy and deadline constraints
TL;DR: In this paper, the average data throughput of a single transmitter sending data over a fading channel to a single user class was maximized by using a dynamic programming formulation that leads to an optimal transmission schedule, first where the present channel state was known just before transmission, and then to the case where the current channel state is unknown before transmission and observed after transmission and evolves according to a Markov process.
