FEC-assisted Nonlinearity Compensation for Coherent Optical Receivers

Research output: Chapter in Book/Report/Conference proceedingArticle in proceedingsResearchpeer-review


This paper presents an overview of fiber nonlinearity compensation (NLC) methods based on digital signal processing (DSP) algorithms assisted by forward error correction (FEC) decoders in coherent optical receivers. The work focuses on DSP schemes that are able to improve the performance of NLC by using hard or soft information feedback from FEC-decoders. Challenges and new research directions are discussed.
