Abstract
Disclosed is a coding and decoding method, in which a certain promised nonzero symbol is appended for coding and decoding, thereby disallowing the presence of a codeword with all-"0" data after coding. The method enables the detection of a fault in an external circuitry by checking the occurrence of an all-"0" received word attributable to the external circuitry.
