DATA PROCESSING DEVICE AND DATA PROCESSING METHOD

摘要

A data processing device and method in which resistance to an error of the code bit of an LDPC code such as a burst error or an erasure can be improved. If two or more code bits of the LDPC (Low Density Parity Check) code is one symbol, a column twist interleaver (24) performs 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 mapped by the one symbol. The data processing device and method can be applied to, e.g., a transmitter to transmit an LDPC code.
