In this paper. we introduce a decode-and-forward multi-hop hybrid free-space optical/radio frequency (FSO/RF) system. The FSO link is assumed to follow Gamma-Gamma distribution with the combined effects of pointing errors and path loss under intensity modulation with direct detection technique. and the RF link is assumed to follow Nakagami-m distribution. https://www.jungleoasisplayground.com/product-category/brushes-pet-combs/
