On the Distribution of the Sum of Gamma-Gamma Variates and Applications in RF and Optical Wireless Communications

The Gamma-Gamma (Γ Γ ) distribution has recently attracted the interest of the research community due to its involvement in various communication systems. In the context of RF wireless communications, Γ Γ distribution accurately models the power statistics in composite shadowing/fading channels as w...
