On the Performance Analysis of Decode-and-Forward Multi-Hop Hybrid FSO/RF Systems With Hard-Switching Configuration

On the Performance Analysis of Decode-and-Forward Multi-Hop Hybrid FSO/RF Systems With Hard-Switching Configuration

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...
