Concerning channel coding, it ’ s for tens of years from the first convolutional code to turbo code recommended by the consultative committee for space data systems ( ccsds ) 在信道编码方面,从最初的卷积码到现在ccsds(consultativecommitteeforspacedatasystems)建议下的turbo码已经经历了几十年的时间。
After that, a demo model of the data system is proposed, which can demonstrate how the real data system works . ( 1 ) what ccsds recommendation for aos is and how aos works are introduced in the first 本文包括了以下几个方面的研究:(1)根据ccsds建议书,对aos的特点、系统构成、业务分类和分层关系等部分作分析介绍。
This thesis is a research on the space station's data system, which is based on the ccsds recommendation for aos . how to design a data system, based on aos for our future space station is discussed in this thesis 该课题以我国未来空间站数据系统为对象,在ccsds对aos建议的基础上,展开了数据系统的网络结构和数据体制等相关的研究。
(2, 1, 7 ) nonsystematic convolutional codes are optimal convolutional codes on the same code length and information bit length condition, so they are adopted as space standard codes by ccsds ( consultative committee for space data systems ) (2,1,7)非系统卷积码在相同的码长和信息长度下为最佳卷积码,因此被ccsds(空间数据系统咨询委员会)采纳为空间标准码。
Consultative committee for space data system ( ccsds ) is an international organization for standardization, which consisted of multinational space organization . ccsds establishes standard communication system structure, protocol, and service for space data system ccsds(空间数据系统咨询委员会)是一个由多国空间组织共同组成的国际标准化组织,它主要为空间数据系统制定标准化的通信体系结构、通信协议与业务。

This paper also studied the international space station ccsds service and the correspondence link . based on the study of the international space station ccsds application, the author designed a space data system example . the ccsds standard is employed in this example 本文还研究分析了国际空间站ccsds业务及通信链路,在参考国际空间站ccsds应用的基础上,设计了一个空间数据系统的实例,该实例完全采用ccsds标准。

After data decoding, this paper analyzes the structure of transfer frame and source packet . the information of every bit is obtained from the frame and packet according to ccsds protocol and furthermore discusses the possibility of recovering the every data field bit ’ s meaning 在得到解码数据后自动对数据帧格式和比特位的信息识别分析,实现了符合ccsds标准格式的各信息位的提取分析,并探讨了完全恢复原信息含义的可能性。
