Title:
TRANSMISSION DEVICE, TRANSMISSION METHOD, RECEIVING DEVICE, AND RECEIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/087774
Kind Code:
A1
Abstract:
The present technology relates to a transmission device, a transmission method, a receiving device and a receiving method that make it possible to ensure good communication quality in the transmission of data using an LDPC code. The code length N is 17280 bits, and LDPC encoding is performed on the basis of an LDPC code check matrix with encoding rates r of 13/16 and 14/16. The LDPC codes include an information bit and a parity bit. The check matrix includes an information matrix corresponding to the information bit, and a parity matrix corresponding to the parity bit. The information matrix is expressed by a check matrix initial value table, and the check matrix initial value table is a prescribed table that shows the position of one element of the information matrix every 360 columns. This technology is applicable to, for example, data transmission using an LDPC code.
