The present invention relates to: a data processing device capable of ensuring good communications quality during data transmission using LDPC code; and a data processing method. In a transmission device, bits b0, b1, and b2 are each replaced by y1, y0, and y2, respectively, when 3-bit code bits stored in storage units having 3 x 16,200/3 bits storage capacity and read one bit at a time from each storage unit are assigned to one symbol, when replacing code bits for LDPC code having a code length of 16,200 bits and an encoding rate of 8/15 with symbol bits for symbols corresponding to any one out of eight signal points prescribed by 8PSK. The positions of replaced code bits, obtained from data sent by the transmission device, are returned to the original positions. The present invention is applicable, e.g., to data transmission, etc., using LDPC code. |
