Error control coding

Error control coding (ECC) is a signal processing technique that protects digital information against transmission and storage errors. Codes that combat randomly distributed errors are called random-error correcting codes. Codes that cope with errors that are clustered together are known as burst-error correcting codes. When data is presented as a stream of binary numbers, bit-oriented codes may be applied. In contrast to this, data might be arranged as words, where each word includes a number of bits. Codes that operate on words are said to be word-oriented codes. The article is limited to linear bit-oriented block codes
