摘要翻译：
本文提出了一种新型的双跳中继辅助混合自由空间光/射频（FSO/RF）通信系统。在该系统中，射频信号从两根天线发射，然后由单根天线中继通过FSO信道转发。本文首次研究了在FSO/RF混合系统发射机上使用Alamouti编码(AC)或天线选择(AS)的性能。FSO链路存在Gamma-Gamma大气湍流，为了更接近实际结果，还考虑了指向误差的影响。首次推导了系统误码率和中断概率的闭式表达式，并通过MATLAB仿真进行了验证。结果表明，在该结构中，AC方案和AS方案的性能差别不大。因此，由于更复杂，功耗和延迟的交流，这是建议的。双跳混合FSO/RF系统显著地提高了系统的性能和可靠性，特别适合于源端和目的地之间无法直接进行RF通信的远距离应用。考虑到这些优点，这种结构特别适合于具有功率和处理限制的移动通信。

英文摘要：
  In this work a novel dual-hop relay-assisted hybrid Free Space Optical / Radio Frequency (FSO / RF) communication system is presented. In this system, RF signal is transmitted from two antennas, and then forwarded by a single antenna relay through FSO channel. This is the first time that performance of using Alamouti Coding (AC) or Antenna Selection (AS) at the transmitter of a hybrid FSO / RF system is investigated. FSO link has Gamma-Gamma atmospheric turbulence, and in order to get closer to the actual results, the effect of pointing error is also considered. For the first time closed-form expressions are derived for Bit Error Rate (BER) and Outage Probability of the proposed system and validated through MATLAB simulations. Results indicate that in this structure, there is slight performance difference between AC and AS schemes. Hence due to more complexity, power consumption and latency of AC, AS is recommended. Dual-hop, hybrid FSO / RF system significantly improves performance and reliability of the system, and is particularly suitable for long-range applications that direct RF communication between source and destination is not possible. Considering these advantages this structure is particularly suitable for mobile communications which has power and processing limitations.
