An implementation method based on arbitrary length data frame header search

为解决卫星海量数据传输多样化问题,提出一种基于任意长度帧头的数据流搜索的实现方法。首先阐述了卫星地面基带处理系统的总体设计流程,然后针对传统的搜索特点介绍了传统的数据帧头搜索方法,最后给出了一种基于任意长度帧头的数据流的实现方法,对该方法进行了详细流程介绍。结果表明,与传统的搜索机制相比较,文章提出的搜索方法具备高速率、高准确率和使用范围广的优点。

In order to solve the problem of diversification of satellite mass data transmission,this paper proposes a data stream search method based on arbitrary length frame header.Firstly,the overall design process of the satellite ground baseband processing system is described.Then target the traditional search features,and the traditional data frame header search method is introduced;Finally,an implementation method based on the data flow of arbitrary length frame headers is given,and the method is introduced in detail.The results show that compared with the traditional search mechanism,the proposed search method has the advantages of high speed,high accuracy and wide range of use.
