摘　　要：针对射频(RF)通信容量不高、保密性不强的问题,提出一种由RF系统和多发射多接收的自由空间光(MIMO-FSO)系统构成的RF/MIMO-FSO混合通信系统。在分析RF系统、MIMO-FSO系统、单输入单输出(SISO)-FSO系统和RF/MIMO-FSO混合通信系统模型的基础上,仿真对比了这4种系统的的误码性能。结果表明:相比RF系统和SISO-FSO系统,RF/MIMO-FSO混合通信系统的误码性能得到了显著提升,在采用相同调制方式下,比SISO-FSO系统平均提高3个数量级左右。For the problem of low communication capacity and low confidentiality of radio frequency(RF) communication,combined RF system and multiple input multiple output free-space optical(MIMO-FSO) system,this paper proposes the RF/MIMO-FSO hybrid communication system.Based on the analysis of RF system,MIMO-FSO system,single input single output(SISO)-FSO system and RF/MIMO-FSO hybrid communication system models,the bit error performance of the these four systems is compared through simulation.The result shows that compared with RF system and SISO-FSO system,the bit error performance of RF/MIMO-FSO hybrid communication system is significantly improved,it is about 3 orders of magnitude higher than SISO-FSO system on average under adopting the same modulation mode.
