Error-Detecting Code Definition/Meaning:
A code that is designed for channel coding, i.e. for
encoding information so that a decoder can detect, with a high probability of
success, whether an intervening channel has caused an error in the signal.
Error-detecting codes are usually block codes, and are generally employed in a
backward error-correction system. The most common error-detecting codes are the cyclic redundancy checks, of which
the simple parity check is a technologically important case.
