The outage performance of FSO system assisted with decode and forward relay is studied using diversity techniques like wavelength and time which helps in mitigating atmospheric turbulence. The channel modelled using Malaga turbulence model with the combined effects of path loss and pointing errors. We derive outage performance analysis for multi hop system using no, wavelength and time diversity schemes, respectively. And we justified the usage of diversity techniques, Because of which the FSO system performance gets enhanced. © 2019 Walter de Gruyter GmbH, Berlin/Boston 2019.
