Title:
TRANSMISSION DEVICE, TRANSMISSION METHOD, RECEPTION DEVICE, AND RECEPTION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/092614
Kind Code:
A1
Abstract:
The present invention relates to a transmission device, a transmission method, a reception device, and a reception method, whereby good communications quality can be ensured during data transmission using LDPC codes. LDPC encoding is performed on the basis of check matrices for LDPC codes having a code length N of 69,120 bits and an encoding rate r of 5/16, 6/16, 7/16, or 8/16. The check matrices include: an A matrix of M1 rows and K columns, indicated by a prescribed value M1 and LDPC code information length K = N×r; a B matrix having a staircase structure of M1 rows and M1 columns; a Z matrix being a zero matrix having M1 rows and N–K–M1 columns; a C matrix having N–K–M1 rows and K+M1 columns; and a D matrix being a unit matrix of N–K–M1 rows and N–K–M1 columns. The A matrix and C matrix are indicated by a check matrix initial value table. The check matrix initial value table indicates the position of one element in the A matrix and the C matrix, for every 360 columns, and is a predetermined table. The present invention is applicable, e.g., to data transmission, etc., using LDPC codes.
