ABSTRACT:
A method for determining r error detection bits of 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. The parity control matrix includes at least two consecutive complementary columns. The present invention also relates to a method for determining a syndrome, as well as a coding and decoding circuit.
