DATA PROCESSING DEVICE, DATA PROCESSING METHOD, AND PROGRAM

摘要

A data processing device, data processing method, and program in which resistance to an error of the code bit of an LDPC code can be improved. If two or more code bits of an LDPC (Low Density Parity Check) code are one symbol and are mapped onto 214 or 216 pieces of signal points, a column twist interleaver (24) performs column twist interleave to change the start position when the code bits are written in the column direction of a memory for each column of the memory as rearrangement processing to rearrange the code bits of the LDPC code so that the code bits corresponding to 1 in one arbitrary row of a check matrix are not included in the one symbol. The data processing device, data processing method, and program can be applied to, e.g., a transmitter to transmit an LDPC code.
