    摘要： A transmission apparatus includes an encoder that codes a data sequence with a parity check matrix, wherein the data sequence includes a final information bit sequence and virtual information bits, and outputs the final information bit sequence and a parity sequence, as LDPC codes, and a transmitter that transmits the LDPC codes as a transmission data. A column length of the parity check matrix is longer than a total length of the final information bit sequence and the parity sequence, by a length of the virtual information bits that are set to “0” and are not transmitted. The total length of the final information bit sequence and the parity sequence has a sequence length corresponding to a length from a first column to a determined column of the parity check matrix. The encoder generates the LDPC codes by using the first column to the determined column among one or more column(s) of the parity check matrix.

    摘要： An encoder and decoder using LDPC-CC (Low Density Parity Check-Convolutional Codes). An encoding rate setting unit sets an encoding rate (s−1)/s (s=z), and an information creating unit sets information including from information Xs,i to information Xz−1,i to zero. A first information computing unit receives information X1,i at time point i to compute the X1(D) term of a formula. A second information computing unit receives information X2,i at time point i to compute the X2(D) term of the formula. A third information computing unit receives information X3,i at time point i to compute the X3(D) term of the formula. A parity computing unit receives parity Pi−1 at time point i−1 to compute the P(D) of the formula. The exclusive OR of the results of the computation is obtained as parity Pi at time i.
