What is it about?
The concept of site diversity is one of the fade mitigation techniques for radio communication system to overcome severe attenuation during an intense rainy condition. In this paper, the performance of experimental findings during the 3-year rainy periods (2011- 2013) at a tropical location, Akure is presented. Time series rain-induced attenuation has been used to estimate and model site diversity fades mitigation over Earth-space links in the region.

Why is it important?
The modified model which incorporated seasonal influences show improved estimation capability better than the ITU-R diversity gain for this location. The overall result will enhance the performance of radio signal transmission along Earth-space paths under intense rainy event in this tropical environment.
Perspectives
I hope this article can be adapted by the system engineers for site and path diversity mitigation necessary to counter the severe rain events at Ku/Ka-bands frequency. The work has been carried out alongside a renowned professor of communication Physics. More than anything else, and if nothing else, I hope you find this article thought-provoking.
