摘　　要：由于未对接收信号进行去噪处理,导致光纤通信链路时延估计存在估计误差大、准确率低的问题,为了解决方法中存在的问题,提出基于边缘计算的高速光纤通信链路时延估计方法。通过边缘计算设计了高速光纤通信网络架构,基于网络架构中的边缘计算层,通过直射链路的方式构建高速光纤通信链路模型,接收光信号,并使用广义相关算法对接收到的信号进行去噪处理,根据去噪处理结果,结合卡尔曼滤波方法与Round-trip算法估计信号时延。实验结果表明,所提方法的高速光纤通信链路时延估计准确率高、效果好,具有较高的实际应用价值。Because the received signal is not de noised,the problem of large estimation error and low accuracy of delay estimation in optical fiber communication link is caused.In order to solve the problem in the method,a study on delay estimation in high-speed optical fiber communication link based on edge computing is proposed.The optical communication network architecture is designed through edge computing.The network communication model is built based on the cloud computing layer in the optical communication network architecture,and the optical signal is obtained.The optical signal is transmitted through the direct link,and the high-speed optical fiber communication model is established.The generalized correlation algorithm is used to denoise the pre filter of the received signal.After the received signal is denoised,the Kalman filtering method and Round trip algorithm are combined to complete the time delay estimation of high-speed optical fiber communication system.The experimental results show that the proposed method has high accuracy,good effect and high practical application value in high-speed optical fiber communication.
