Probabilistically-Shaped Coded Modulation with Hard Decision Decoding for Coherent Optical Systems

Published 5 May 2017 in cs.IT and math.IT | (1705.02283v1)

Abstract: We consider probabilistic shaping to maximize the achievable information rate of coded modulation (CM) with hard decision decoding. The proposed scheme using binary staircase codes outperforms its uniform CM counterpart by more than 1.3 dB for 64-QAM and 5 bits/symbol.
