摘要
针对传统方法存在数据预处理时间长、无法消除冗余数据等问题,提出一种基于变分率时域技术的光通信数据预处理方法。首先采用变分率时域技术提取光通信中的冗余数据特征,然后运用线性频谱分析法对冗余数据特征进行分类,根据分类结果可实现冗余数据消除和处理,最后进行了光通信数据预处理仿真实验,结果表明,本文方法对源数据影响较低,运算过程简单,提高了光通信数据预处理效率,为提升光通信冗余数据的消除效率提供了有力的依据。
Aiming at the problems of long data preprocessing time and unable to eliminate redundant data in traditional methods,a data preprocessing method of optical communication based on variation rate time domain technology is proposed. Firstly,the variation rate time domain technology is used to extract redundant data features in optical communication. Then,the linear spectrum analysis method is used to classify the redundant data features. According to the classification results,the redundant data can be eliminated and processed. Finally,the simulation experiment of data preprocessing in optical communication is carried out. The results show that the method in this paper has low impact on source data,which has simple operation process and improves the light quality. The efficiency of communication data preprocessing provides a powerful basis for improving the efficiency of eliminating redundant data in optical communication.
