摘要 通过对混合FSO/RF系统雨、雾天气下的误码率进行研究,从仿真结果中分析出雾是影响FSO系统的最主要因素,得出RF系统可以弥补FSO链路雾天缺陷的结论。经分析对比出雨天对FSO系统的影响要远小于雾天对FSO系统的影响。同时还对雨、雾天气情况下的开关键控(OOK)和脉冲相位调制(PPM)的性能进行了仿真分析。验证了在无线光通信系统中,PPM调制系统性能要优于OOK调制系统的性能。 In this paper,BER of hybrid FSO/RF systems in fog and rain conditions is studied.From the simulation results,fog is a dominant challenge for FSO systems,while RF systems can make up for this deficiency.However,rain attenuation of FSO systems is comparatively less important.Additionally,FSO systems employing on-off keying(OOK) and pulse-position modulation(PPM) in rain and fog conditions are discussed.PPM has better performance than OOK modulation in the wireless optical systems.
