Simple receiver with soft decision forward error correction for binary amplitude modulation
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. (laser applications and other topics in quantum electronics)
