Abstract: A simple receiver with soft decision forward error correction (FEC) based on two comparators is proposed. It is shown that the gain in the optical signal-to-noise ratio (OSNR), as compared with conventional receivers with hard decision FEC, can reach 0.5 dB. Some design variants of such detectors are presented.

Keywords: receiver with soft decision FEC, error correction encoding, binary communication channel, mutual information, channel capacity, Q-factor.
