海明码在提高导航数据传输可靠性中的应用

The Application of Hamming Code in Improvement of Navigation Transmission’s Reliability of Date

介绍了海明码的编码原理和构造方法,分析以太网络进行信息传输时出现的误码问题,提出利用海明码编码的纠错能力进行数据纠错,并以软件实现的方式说明海明码在导航系统中的应用,给出收发两端的算法流程。试验结果表明,应用海明码编码技术可以有效地提高系统网络数据传输的可靠性。

This paper puts forward a new method of data correcting by Hamming Code error-correcting capability. The principle of coding and the elements of formatting in Hamming Code are introduced for the further research to improve the reliability of transmit-ting data. Additionally,the application of Hamming Code in the navigation system is illustrated in software,in which the flow of the whole process and the details of the arithmetic are given both in the sending and receiving terminals. The results indicate the capa-bility of Hamming Code in advancing the reliability of transmitting data accurately in the whole system.
