Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A transmission apparatus comprising: 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 low-density parity-check (LDPC) codes; and a transmitter that transmits the LDPC codes as a transmission data; wherein “n” number (where n is an integer equal to or greater than…
