Title: Code error correcting circuit
Inventor: ITOI TETSUSHI
IPC: H03M13/00
Filed: 1988-04-30
Abstract: PURPOSE:To attain accurate error correction in a short period through the use of a small scale conversion table by resolving an error position equation required for two error correction by using the conversion table with setting only an absolute term to be the function of syndromes at the time of decoding a read Solomon code where the minimum distance of inter-codes show '5'. CONSTITUTION:When a code error correction circuit 11 decodes the read Solomon code where the minimum distance of inter-codes show '5', said circuit recognizes that the coefficients alpha, beta and gamma in respective terms, which are expressed by the function of four syndromes S0-S3, do not show zero, and executes linear conversion W=B1Z where only the absolute term (gamma/alpha)/(beta/alpha)<2>=B2/B is expressed by the function of the syndromes on the error position equation alphaW<2>+betaW+gamma=0 where two error positions X1 and X2 are set to roots, whereby two roots are obtained by collating the conversion table where the absolute term B2/B is set to be an index. Before two error correction is executed, it is recognized that S0S1 0 and alphabetagamma 0, and an operation required for error correction is started after the probability of the cases of non-correction one error correction and correction impossibility are excluded.
