摘要: In this study, the multivariate gamma-gamma (G-G) distribution with exponential correlation is introduced and studied. Rapidly convergent infinite series representations are derived for joint G-G probability density, cumulative moment generating functions. Based on these formulas, performance of radio frequency wireless systems diversity reception in presence composite multipath shadow fading analysed. Furthermore, single-input-multiple-output free space optical communication impaired by atmospheric turbulence investigated. The correctness proposed analysis demonstrated through various numerically evaluated results compared equivalent computer simulation ones.
