    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 predetermined column of the parity check matrix. The encoder generates the LDPC codes by using the first column to the predetermined column among one or more column(s) of the parity check matrix.

    摘要： There is provided an encoder that provides a termination sequence with a simple structure for LDPC-CC encoding and reduces an amount of the termination sequence transmitted to a transmission line. The LDPC-CC encoder connects a first encoder to a second encoder to perform encoding and thereby carry out LDPC-CC encoding, the first encoder performing encoding based on an partial parity check matrix for information bits obtained by extracting a sequence corresponding to the information bits in a parity check matrix and the second encoder performing encoding based on a partial parity check matrix for parity bits obtained by extracting a sequence corresponding to the parity bits in the parity check matrix. A termination sequence generator generates a termination sequence including the same number of bits as the memory length of the first encoder and provides the generated termination sequence as an input sequence.

    摘要： An encoder and decoder using LDPC-CC (Low Density Parity Check—Convolutional Codes) is disclosed. In the encoder (200), an encoding rate setting unit (250) sets an encoding rate (s−1)/s (s=z), and an information creating unit (210) sets information including from information Xs,i to information Xz-1,i to zero. A first information computing unit (220-1) receives information X1,i at time point i to compute the X1(D) term of formula (1). A second information computing unit (220-2) receives information X2,i at time point i to compute the X2(D) term of formula (1). A third information computing unit (220-3) receives information X3,i at time point i to compute the X3(D) term of formula (1). A parity computing unit (230) receives parity Pi−1 at time point i−1 to compute the P(D) of formula (1). The exclusive OR of the results of the computation is obtained as parity Pi at time i. Ax.
