| 摘 要： | 为准确评价混合射频/ 自由空间光通信(RF/ FSO: Radio鄄Frequency/ Free Space Optics) 中继系统性能,利用Meijer's G 函数推导得到混合RF/ FSO 中继系统端到端中断概率闭合解析表达式。该混合RF/ FSO 中继系统采用放大转发中继、RF(Radio Frequency)双天线发射技术。RF 信道衰落服从Rayleigh 分布, FSO(Free Space Optics)信道衰落服从M 分布。蒙特卡洛仿真验证了推导结果的准确性。

| Abstract: | In order to accurately evaluate the hybridradio frequency/free space optical RF/FSO ( Rradio-Frequency/Free-Space Optics) relay system performance, the closed form analytical expression of end to end outage probability of hybrid RF/FSO relay system is derived by using the Meijer's G function. The hybrid RF/FSO relay system uses the amplification and forward relay and the RF ( Radio-Frequency ) dual antenna transmission technology. The fading of the RF channel obeys the Rayleigh distribution, and the fading of the FSO ( Free-Space Optics) channel obeys the M distribution. The Monte Carlo simulation verifies the accuracy of the derivation. |
