On the Performance under Hard and Soft Bitwise Mismatched-Decoding
arXiv:2002.00560 · doi:10.1364/OFC.2020.Th1I.5
Abstract
We investigated a suitable auxiliary channel setting and the gap between Q-factors with hard and soft demapping. The system margin definition should be reconsidered for systems employing complex coded modulation with soft forward error correction.
