Title:
TRANSMISSION METHOD AND RECEPTION DEVICE
Document Type and Number:
Japanese Patent JP2019126017
Kind Code:
A
Abstract:
To ensure favorable communication quality in data transmission using an LDPC code.SOLUTION: In group-wise interleaving, an LDPC code with a code length N of 17280 bits is interleaved in the unit of bit groups 0 to 47 respectively having 360 bits. In group-wise deinterleaving, an arrangement of the LDPC code after the group-wise interleaving is restored to an original arrangement. The present technique can be applied, for example, to a case where data transmission using LDPC code is carried out.SELECTED DRAWING: Figure 108
