error-correcting code

Computer

A code that is designed for channel coding, i.e. for encoding information so that a decoder can correct, with a high probability of success, any errors caused in the signal by an intervening noisy channel.
Error-correcting codes may be block codes or convolutional codes, and in either case are employed in a forward error-correction system. The most common error-correcting block codes are the Hamming codes, Bose–Chaudhuri–Hocquenghem (BCH) codes, Reed–Solomon (RS) codes, simplex codes, and the Golay (23, 12) code.
Since errors may be corrected by detecting them and requesting retransmission, the process of error correction is sometimes taken to include backward error-correction systems and, hence, error-detecting codes.
See also coding bounds, coding theory, Shannon’s model.

Electronics and Electrical Engineering

Techniques for encoding data as sequences of bits in a way that makes it possible to detect and correct a certain number of errors where bits have been changed as a result of noise and circuit faults. All ECC techniques work by adding extra bits to the data, in such a way as to ensure some simple property holds of all of the bits in the code. Any subsequent errors in the data will result in the property failing to hold, making it easy to detect that an error has occurred. Most techniques involve Hamming codes or computing checksums by adding up all the bit values with a specially designed formula. See also digital codes; digital communications; parity check.
