Patent Searching and Data


Title:
TRANSMISSION DEVICE, TRANSMISSION METHOD, RECEPTION DEVICE, AND RECEPTION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/087782
Kind Code:
A1
Abstract:
The present technology relates to a transmission device, a transmission method, a reception device and a reception 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 parity check matrix with an encoding rate r of 7/16 or 8/16. The LDPC code includes 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, which 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.
