Parsing of the Check and Rectification Principle of Hamming Code
Gan Jia-bao · Microcomputer applications · 2007
Hamming code is a widely used technology to carry out check and rectification in digital communication filed, it's usedwith insertingsome check bits to data when transfer is processing. Many textbooks on network and communication introduce thistechnology. But nearly all explanation is hard to understand. For example:1) There is few explanation to this formula:2k-1≥m+k(among which, m is the length of data and k is the length of inserting digit)2)There is no explanation to easily understand the principle of check and rectification.In this article, I gives some examples and help readers to understand the principle easier step by step.
