Secrecy Outage Analysis of Mixed RF-FSO Systems With Channel Imperfection
IEEE Photonics Journal, 2018 We analyze the secrecy outage performance of a mixed radio frequency-free space optical (RF-FSO) transmission system with imperfect channel state information (CSI). We deal with a single-input multiple-output wiretap model, where a base station (works as
