Abstract :
A novel DSP-based FWM compensation scheme for 112 Gb/s CO-OFDM based on decision-feedback-aided frequency-shaped Volterra nonlinear filtering, with low O(M log M) realization complexity, improves the worst Q-factor by ~7 dB at 2000 Km, outperforming a prior low-complexity nonlinear compensation scheme by ~2 dB.
