研究了Exponentiated Weibull(EW)大气湍流信道下航空激光通信的性能,综合考虑大气湍流及气动光学效应的影响,利用Meijer′s G函数推导出了航空激光通信链路的性能指标的闭合表达式,包括平均误码率(BER)、中断概率及平均信道容量。在不同的航空飞行条件下,根据平均BER、中断概率和平均容量闭合表达式分别给出了数值仿真实例,分析了航空飞行高度、传输距离、信噪比(SNR)与航空激光通信系统性能的关系,同时分析了孔径平均效应对航空激光通信链路性能改善作用。
The performance of airborne laser communication under the atmosphere turbulence channel of Exponentiated Weibull (EW) was studied. The closed expression of the performance index of the aviation laser communication link was deduced by Meijer’s G function considering the effects of atmospheric turbulence and aerodynamic optics. Including average bit error rate (BER), outage probability and average channel capacity. Under different conditions of aviation flight, numerical simulation examples are given respectively based on the average BER, the probability of discontinuity and the closed form of the average capacity. The flight altitude, transmission distance, signal to noise ratio (SNR) and the performance of airborne laser communication system At the same time, the averaging effect of aperture was analyzed to improve the performance of aeronautical laser communication links.
