Abstract:
1. A transmission apparatus comprising: a Low Density Parity Check (LDPC) encoding section that generates a first encoded data sequence by encoding transmission data using a code defined by a parity check matrix including a plurality of columns that are different in column weight, and selects, among the first encoded data sequence, an encoded data sequence as a second encoded data sequence based on column weights of the parity check matrix, the number of “1”s of a column vector, which is a column weight, corresponding to the second encoded data sequence, is equal to or greater than the number of “1”s of a column vector, which is a column weight, corresponding to an encoded data sequence not selected from the first encoded data sequence; and a transmission section that transmits the first encoded data sequence and the second encoded data sequence, wherein: a data length of the second encoded data sequence is shorter than a data length of the first encoded data sequence.
