为了建立同频干扰条件下的混合射频/自由空间光(Radio Frequency/Free Space optical, RF/FSO)航空中继通信系统链路精确模型,提出多用户分集(Multi-User Diversity, MUD)的航空平台RF/FSO混合链路性能分析方法.以独立且同分布的Nakagami-m衰落信道表征射频(Radio Frequency, RF)用户信号和同频干扰(Co-Channel Interference, CCI)信号信道;构建了指数Weibull分布大气湍流与Rayleigh分布指向误差的FSO信道传输模型;在电光转换中继节点采用解码转发协议降低噪声累积.基于系统端到端等价信噪比累积分布函数,获得了RF/FSO混合链路中断概率及平均误码率表达式.研究结果表明,采用相干二进制相移键控调制时,系统误码性能最优;可通过增加用户数的方式来减弱干扰信号的影响. |

In order to establish an accurate model of the hybrid radio frequency/free space optical(Radio Frequency/ Free Space optical, RF/FSO) aviation relay communication system link under the condition of co-channel interference, a multi-user diversity(Multi-User Diversity, MUD) airborne platform RF/FSO hybrid link performance analysis method is proposed. The independent and identically distributed Nakagami-m fading channel is used to characterize the RF user signal and the co-channel interference(Co-Channel Interference, CCI) signal channel, while the FSO link between relay to destination is assumed to be affected by Exponentiated Weibull distributed atmospheric turbulence and the Rayleigh distributed pointing error. The decoding and forwarding protocol is adopted at the relay node to avoid accumulation of noise. Based on the cumulative distribution function of the system's end-to-end equivalent signal-to-noise ratio, the closed expressions for link outage probability and average bit error rate are derived. The research results show that when using coherent binary phase shift keying modulation, the system has the best error performance. The influence of interference signals can be reduced by increasing the number of users. |
