Abstract

Nonlinear equalizers based on nonlinear Volterra theory and maximum-likelihood sequence estimators (MLSE) are investigated to mitigate the nonlinear distortions resulting from the incomplete sideband suppression in optical single side band modulation (OSSB) systems. Through theoretical analysis and simulations, we demonstrate that electrical dispersion compensation (EDC) by using these nonlinear equalizers can achieve better performance compared to conventional analog equalizers including feedforward equalizers (FFE) and decision feedback equalizers (DFE).
