摘　　要：针对目前方法预测移动通讯链路损耗时无法有效检测到链路的衰减曲线,导致预测精度低、预测性能较差。为此,提出了一种基于遍历微元法的可见光移动通讯链路损耗动态预测方法。该方法利用马尔可夫移动模型提取移动通讯链路数据的运动兴衰特征。根据获取的特征构建非直视非共面的可见光单次散射模型,并分析模型中的数据。采用遍历微元法生成可见光移动通讯链路的损耗方程,通过计算完成可见光移动通讯链路损耗的动态预测。实验结果表明,该方法在链路损耗预测时可以有效检测出链路的衰减曲线,预测精度高,且预测性能较好。The current methods cannot detect the attenuation curve of mobile communication link loss effectively,which leads to low prediction accuracy and poor prediction performance.Therefore,a dynamic prediction method of visible light mobile communication link loss based on ergodic infinitesimal method is proposed.In this method,the Markov mobility model is used to extract the motion characteristics of mobile communication link data.According to the obtained features,the visible light single scattering model of non-direct viewing and non-coplanar is constructed,and the data in the model is analyzed.The loss equation of visible light mobile communication link is generated by the ergodic infinitesimal method,and the dynamic prediction of visible light mobile communication link loss is completed by calculation.Experimental results show that this method can effectively detect the attenuation curve of the link in the link loss prediction,with high prediction accuracy and good prediction performance.
