Patent Searching and Data


Title:
TRANSMISSION METHOD AND RECEPTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/143012
Kind Code:
A1
Abstract:
The present invention pertains to a transmission method and a reception device which make it possible to ensure excellent communication quality in data transfer using LDPC codes. In group-wise interleaving, an LDPC code having a code length N of 69,120 bits is interleaved on a bit group basis of 360 bits per group. In group-wise de-interleaving, the order of the interleaved LDPC code is restored to the original order. This invention can be applied, for example, to data transfer and the like using LDPC codes.
