A study on the effectiveness of turbo equalization with FEC for nonlinearity compensation in coherent WDM transmissions

We evaluate the performance improvement in the presence of fiber nonlinearity obtained using a Turbo equalizer. Numerical simulation shows that Turbo equalization offers an improvement of 0.8 dB in a 100 Gb/s NZ-DSF transmission, even with only 5 taps for the MAP estimation.
