Constant weight codes for correcting symmetric errors and detecting unidirectional errors
Mao‐Chao Lin · IEEE Transactions on Computers · 1993
Proposes two classes of constant weight codes, which can be used for correcting t symmetric errors and simultaneously detecting all unidirectional errors. Codes in the first class are in quasi-systematic form and codes in the second class are in systematic form. Since each codeword of codes in both classes can be divided into a data part and a parity check part, the proposed codes have the merit of easily mapping messages into codewords.>
