Abstract
Provided is an optical transmission/reception device including an error correction decoding unit () for decoding a received sequence encoded with an LDPC code, in which the error correction decoding unit () is configured to perform decoding processing using a parity check matrix () of a spatially-coupled LDPC code, which includes a plurality of parity check sub-matrices () combined with each other, in which the decoding processing is windowed decoding processing that uses a window () over one or more parity check sub-matrices (), and in which a window size of the window () and a decoding iteration count due to throughput and requested correction performance are variable and input from a control circuit () connected to the error correction decoding device ().
