    摘要: The error correcting decoding device of the present invention performs Low-Density Parity-Check (LDPC) decoding which accommodates a plurality of code rates while sharing circuits to suppress increase in circuit scale. If the set code rate is a second code rate which is a higher code rate than a first code rate, a column processing and row processing calculating unit (120A) uses a distributed submatrix in which a number of columns are selected and combined, wherein the number of columns is equal in number to the number of columns with which a first submatrix is constructed from a distributed check matrix corresponding to a second check matrix which accommodates the second code rate. At this time, the column processing and row processing calculating unit (120A) uses a distributed submatrix such that the row degree is less than or equal to the row degree of the first submatrix.

    摘要: Positions holding different bit values between a first code word, which is obtained by coding an information bit sequence based on a coding method utilizing quasi-cyclic codes, and a second code word, which has the close Hamming distance from the first code word and satisfies a parity check of the coding method, are identified. Thereafter, a code word is generated by inserting bit values known to the transmitter and receiver into the identified positions of the information bit sequence and coding the information bit sequence. Upon reception of a signal based on the generated code word, the receiver judges whether known bit values held by corresponding positions in a code word obtained by decoding the received signal are the same as preset bit values. If the judgment result is negative, the code word based on the received signal is judges as erroneous even when it satisfies the parity check.
