Modified Decision Feedback Equalizers for Nonlinearity Compensation in Coherent PAM4 Transmission System
To address chromatic dispersion (CD) and nonlinear impairments in coherent optical four-level pulse amplitude modulation (PAM4) systems, we propose a magnitude-assisted decision feedback equalizer (MA-DFE). The proposed scheme utilizes signal amplitude information to construct the error function, wh...
