A method is described for constructing a multibit error-correction/all unidirectional error-detection (EC/AUED) code, wherein k information bits are first encoded into a systematic [n', k, 2t+1] EC code, and r* bits are appended therein to enable AUED capability, the extra r* bits being a function of the weight of the codeword of length n' and are obtained through a table look-up.
