Title:
TRANSMISSION DEVICE, TRANSMISSION METHOD, RECEIVING DEVICE AND RECEIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/087780
Kind Code:
A1
Abstract:
The present technology relates to a transmission device, a transmission method, a receiving device and a receiving method which make it possible to ensure good communication quality in data transmission 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 2/16, 3/16 and 4/16. The check matrix includes: an A matrix of M rows and K columns expressed by a prescribed value M1 and an LDPC code information length K=N×r; a B matrix with a hierarchical structure of M1 rows and M1 columns; a z matrix which is a zero matrix of M1 rows and N-K-M1 columns; a C matrix of N-K-M1 rows and K+M1 columns; and a D matrix which is a unit matrix of N-K-M1 rows and N-K-M1 columns. The A matrix and the C matrix are expressed by a check matrix initial value table. The check matrix initial value table is a prescribed table that shows the position of one element of the A matrix and the C matrix every 360 columns. This technology is applicable to, for example, data transmission using an LDPC code.
