标题： On the Performance of RF-FSO Links with and without Hybrid ARQ

摘要： 本文研究了假设接收端具有完美信道状态信息（CSI）的混合射频（RF）和自由空间光（FSO）链路的性能。考虑带有和不带有混合自动重传请求（HARQ）的情况，我们推导出了消息解码概率以及RF-FSO设置的吞吐量和中断概率的闭合表达式。我们还评估了自适应功率分配和不同信道条件对吞吐量和中断概率的影响。结果显示了RF-FSO链路在各种条件下的效率。 显示英文摘要

摘要： This paper studies the performance of hybrid radio-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 adaptive power allocation and different channel conditions on the throughput and the outage probability. The results show the efficiency of the RF-FSO links in different conditions.
