Title:
DECODING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/250390
Kind Code:
A1
Abstract:
A decoder (1) which is a decoding device is provided with: an error correction decoding unit (12) which performs, on received data resulting from spatial coupling low-density parity-check coding, an error correction decoding process in which a decoding process is repeatedly performed by the number of times of a decoding iteration count and the window size indicated by a decoding parameter; and a decoding parameter control unit (14) which updates the decoding parameter on the basis of a decoding result obtained through the decoding process that is repeatedly performed.
