Abstract
A decoding device for decoding an input codeword bit stream using a generator polynomial represented by the product of a plurality of sub-polynomials disclosed. The decoding device comprises a plurality of serial concatenated decoders each having different generator polynomials, wherein a product of the different generator polynomials becomes said generator polynomial, the different generator polynomials are represented by the different sub-polynomials or by a product thereof, and a first-stage decoder out of the serial concatenated decoders receives said codeword bit stream. The decoders each perform soft decision, and the codeword is a linear block code.
