Abstract:
1. A coding device for coding an information bit sequence and outputting the coded information bit sequence, comprising: a determining unit operable to, in accordance with an applied coding method that utilizes a quasi-cyclic code, determine at least one bit position in the information bit sequence as an insertion position into which a false detection check bit value for preventing a receiver device from falsely detecting an erroneous code word as an error-free code word is to be inserted, wherein a bit position in a first code word which corresponds to the insertion position holds a different bit value from a bit position in at least one second code word which corresponds to the insertion position, the first code word being obtained by coding the information bit sequence in accordance with the coding method, the second code word being judged as an error-free code word by a parity check of the coding method, and the second code word being different from the first code word by the minimum Hamming distance; an inserting unit operable to generate a pre-coding bit sequence by inserting the false detection check bit value into the insertion position of the information bit sequence; and a coding unit operable to generate a third code word by coding the pre-coding bit sequence in accordance with the coding method.
