On the Performance of HARQ-Based RF-FSO Links

• This paper studies the performance of the hybridradio-frequency (RF) and free-space optical (FSO) links assuming perfect channel state information (CSI) at the receiver. Considering the cases with and without hybrid automatic repeat request (HARQ), we derive closed-form expressions for the message decoding probabilities as well as the throughput and the outage probability of the RF-FSO setups. We also evaluate the effect of different channel conditions on the throughput and the outageprobability. The results show the efficiency of the RF-FSO links in different conditions.
