Performance of free-space optical communications using SC-QAM signals over strong atmospheric turbulence and pointing errors
We take into account atmospheric attenuation, atmospheric turbulence and pointing errors. In order to model atmospheric turbulence, we employ a gamma-gamma distribution for strong turbulent condition.

Sun-Tracking Microwave Radiometry: All-Weather Estimation of Atmospheric Path Attenuation at $Ka$ -, $V$ -, and $W$ -Band
Abstract: Sun-tracking (ST) microwave radiometry is a ground-based technique where the Sun is used as a beacon source. The atmospheric antenna noise temperature is measured by alternately pointing ...
