Analysis of the Singularity Avoidance Capability of Constant Modulus Algorithms in Coherent Optical Fibre Communication Systems
2023 Asia Communications and Photonics Conference/2023 International Photonics and Optoelectronics Meetings (ACP/POEM)(2023)
Abstract
Constant Modulus Algorithm (CMA) in dual-polarization optical coherent transmission is revisited for optical access. We introduce a refined CMA, exhibit singularity-free operation up to 5 ps/km
