Abstract:
An optical receiver includes: a first calculation unit that obtains a log likelihood ratio for each M-dimension (M is a natural number), based on a received signal; and a second calculation unit that obtains a log likelihood ratio of an N dimensional symbol (N is a natural number), based on the log likelihood ratio for each M-dimension.

Claim (Index 3):
An optical transmission device comprising:\n the optical transmitter according to  claim 1 ; and\n an optical receiver, \n wherein the optical receiver comprises: \n a soft determination error correction code encoding circuit that adds, to an input bit string, a redundant bit used for soft determination error correction; \n an N-dimensional encoding circuit that associates the input bit string to which the redundant bit is added with a signal point arrangement of a N dimensional space (N is a natural number); \n an N-dimensional symbol mapping circuit that generates a modulation signal corresponding to an N-dimensional symbol, based on an output from the N-dimensional encoding circuit; and \n an optical modulation circuit that modulates light using the modulation signal and outputs it.
