Abstract: A method for determining r error detection bits that can be associated with a word of m bits to be coded, including the step of calculating the product of a vector with m components representative of the word of m bits to be coded and of a parity control matrix of dimension rnullm. The parity control matrix is such that each column of matrix includes an odd number of null1snull greater than or equal to three. The present invention also relates to a method for determining a syndrome.
