Abstract In this research work, the analysis of mixed user diversity radio frequency (RF)/ spatial diversity free space optics (FSO) relaying has been presented. The multi user diversity (MUD) aided RF link has been modeled using the α − μ distribution whereas the statistics of spatial diversity on the FSO link have been derived with the help of mixture Gamma turbulence model which also takes into account for the pointing errors. For the considered system model, the exact closed-form expressions for the outage probability and bit error rate (BER) have been derived. Furthermore, the high signal-to-noise-ratio (SNR) analysis has been performed to present the asymptotic expressions for the outage probability and BER. Finally, numerical examples have been demonstrated which are verified using the Monte-Carlo simulations.
