Cascaded Shadowed UAV-to-Ground Channels

In this paper, cascaded shadowed uncrewed aerial vehicles (UAVs)-to-ground fading channels are introduced and mathematically characterized. This is done in order to provide a comprehensive statistical analysis by deriving expressions for their probability density function (PDF) and cumulative distribution function (CDF). This lays the groundwork for modeling and analyzing the reliability of wireless communication systems operating over such channels. Utilizing these expressions, key metrics such as the outage probability, average channel capacity, and average bit error probability are derived. The Meijer G function is employed to express these metrics in closed-form expressions. To validate our analysis, Monte-Carlo simulations are conducted, demonstrating the effectiveness and accuracy of our analytical framework.
