摘要
为分析光通信信息传输误差影响因素,准确评估光通信信息传输误差影响因素对信息传输质量的影响,构建基于光通信信息传输误差影响因素筛选的传输误差分析模型,筛选光通信信息传输误差影响因素,将影响光通信信息传输精度的大气湍流、背景光、高斯光束三个因素依次进行建模分析;并使用基于支持向量机的光通信信息传输质量评估模型,评估大气湍流、背景光、高斯光束三个因素影响下,光通信信息传输误差。研究结果显示:大气湍流强度、背景光强度、高斯光束发散角变大,光通信信息传输误差变大,则所筛选的影响因素均对光通信信息传输质量存在重要影响;所构建模型对光通信信息传输误差的评估精度值最小值为0.98,最大值为0.99,评估精度较高。
In order to analyse the influence factors of optical communication information transmission error and accurately evaluate the influence of optical communication information transmission error influence factors on information transmission quality,a transmission error analysis model based on screening optical communication information transmission error influencing factors are constructed,and atmospheric turbulence,background light and Gaussian beam that will affect the optical communication information transmission accuracy are screened The three factors are modelled and analysed in turn;and the optical communication information transmission quality evaluation model based on support vector machine is used to evaluate the optical communication information transmission error under the influence of atmospheric turbulence,background light and Gaussian beam. The results show that: the atmospheric turbulence intensity,background light intensity,Gaussian beam divergence angle increase,the optical communication information transmission error increases,then the selected influencing factors have a meaningful impact on the optical communication information transmission quality;the minimum value of the evaluation accuracy of the model for optical communication information transmission error is 0. 98,the maximum value is 0. 99,the evaluation accuracy is high.
