On the Sum of Inverse Gamma RVs and its Application to Wireless Communications Networks

Petros S. Bithas, Liang Yang, Qiuming Zhu وآخرون · 2026 · 10.1109/tvt.2026.3702729

Investigating the statistics of the sum of random variables (RVs) is fundamental in wireless communication systems, as it can be used to accurately estimate their performance. In this paper, exact closed-form expressions are derived for the probability density function (PDF) and cumulative distribution function (CDF) o …
