云计算环境下光纤通信容易受到大数据扰动的码元干扰,需要进行码元干扰抑制,为了提高光纤通信的稳定性和准确性,提出一种基于最大似然检测和判决反馈均衡的云计算环境下的光纤通信平台抗干扰方法。构建光纤通信平台的数据传输信道分布模型,在单帧数据传输时间内采用多径扩展覆盖方法进行信道均衡设计,采用最大似然检测将单帧数据中码间干扰检测出来,结合判决反馈均衡方法抑制频率选择性衰落,实现光纤通信平台的抗干扰设计。仿真结果表明,采用该方法进行光纤通信抗干扰设计,提高通信平台的输出信噪比,降低输出误码率。

Cloud computing environment is vulnerable to code elements interference of big data perturbation in the optical fiber communication,so it needs code elements interference suppression. In order to improve the stability and accuracy of optical fiber communication,proposes an optical fiber communication platform anti-jamming method based on maximum likelihood detection and decision feedback equalization in cloud computing environment. Construct the data transmission channel distribution model of optical fiber communication platform. Design channel equalization by multipath extended coverage method within transmission time of single frame. Detect inter-symbol interference in single frame data by using the maximum likelihood detection. Combine with the decision feedback equalization method to suppress frequency selective fading,and realize anti jamming design of optical fiber communication platform. The simulation results show that this design improves the output SNR of communication platform and reduces the output bit error rate.
