Abstract
A circuitry is proposed for the correction of errors in a possibly erroneous binary word v'=v′, . . . , v′relative to a codeword v=v, . . . , v, in particular 3-bit errors containing an adjacent 2-bit error (burst error). The circuitry comprises a syndrome generator and a decoder. A modified BCH is used wherein n′ column vectors of a first BCH code submatrix are paired as column vector pairs so that a componentwise XOR combination of the two column vectors of each column vector pair produces an identical column vector K that is different from all column vectors of the first BCH submatrix. A second BCH submatrix comprises corresponding column vectors as the third power, according to Galois field arithmetic, of the column vector in the first BCH submatrix. The syndrome generated by the syndrome generator can be checked against the columns of the first and second submatrices.
