Definition

An error-correcting code is a technique whereby a transmitted codeword contains extra characters whose purpose is to detect whether the codeword has been corrupted during transmission.


Historical Note

The theory of error-correcting codes was initially developed by Marcel Jules Edouard Golay and Richard Wesley Hamming.

The method has since been used to correct transmission errors on messages received from outer space on space missions to the planets.

As a result, detailed close-up pictures of the planets have been obtained.
