Title:
TRANSMISSION METHOD AND RECEPTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/142684
Kind Code:
A1
Abstract:
This invention pertains to a transmission method and a reception device with which it is possible to ensure excellent communication quality in data transmission using LDPC coding. In groupwise interleaving, an LDPC code having a code length N of 17280 bits is interleaved in units of bit groups 0 to 47, each of the bit groups being 360 bits long. In group-wise deinterleaving, the interleaved LDPC code is restored to the original ordering thereof. This invention can be applied when performing data transmission using LDPC coding, for example.
