Title:
DATA-PROCESSING DEVICE AND DATA-PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2012/098982
Kind Code:
A1
Abstract:
This technology relates to a data-processing device and data-processing method having increased tolerance for data errors. With an LDPC code mapped to 16 signal points, said LDPC code having a block size of 16,200 bits and a code rate of 1/5, 4/15, or 1/3, a demultiplexer performs the following rearrangement, with "bi" representing the (i+1)th of 4×2 code bits and "yi" representing the (i+1)th of 4×2 symbol bits for two consecutive symbols, counting in both cases from the most significant bit: b0 to y4, b1 to y3, b2 to y2, b3 to y1, b4 to y6, b5 to y5, b6 to y7, and b7 to y0. The present invention can be applied, for example, to a transmission system for transmitting LDPC codes.
