Title:
TRANSMISSION DEVICE, TRANSMISSION METHOD, RECEPTION DEVICE, AND RECEPTION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/092616
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 9/16 or 10/16. The LDPC codes include information bits and parity bits. The check matrices include information matrices corresponding to the information bits and parity matrices corresponding to the parity bits. The information matrices are described by a check matrix initial value table. The check matrix initial value table indicates the position of one element in an information matrix, for every 360 columns, and is a predetermined table. The present invention is applicable, e.g., to data transmission, etc., using LDPC codes.
