In order to improve the accuracy of information transmission, we introduce error control techniques. The technology uses a reliable and effective method of channel coding to achieve. Error-correcting code is an error control techniques have been widely used in various communications systems and computer systems, mainly used for error-correcting coding errors in digital control systems, to ensure communication, storage, media players and digital transmission of information transfer the quality of the process of great significance, is the communications, information-type knowledge structure of subjects an indispensable part. This article introduces a systematic error-correcting codes in digital systems in the use and development, as well as the basic principles of error-correcting codes and meaning of commonly used error-correcting codes and classified briefings, as well as Vc + +6.0, introduced the basic knowledge, and how Vc + + to achieve the application of hamming code encoder and decoder.
