Abrégé
Provided is an optical transmission/reception device including: an error correction encoding unit (23) configured to encode a sequence to be transmitted with one type of LDPC code; and an error correction decoding unit (36) configured to decode a received sequence encoded with the LDPC code. The error correction decoding unit (36) performs decoding processing for the received sequence based on a check matrix of an LDPC convolutional code. The decoding processing is windowed decoding processing, which is performed by using a window extending over one or more check submatrices. A window size of the window and a decoding iteration count are configured to be variable, and the window size and the decoding iteration count are input from a control circuit connected to the error correction decoding unit.
