Abstract :
We propose a simplified Volterra series nonlinear equalizer (VSNE) based on a pruned symmetric reconstruction of the third-order kernel. In a 224 Gb/s PM-16QAM transmission system with 1600 km, the number of complex multiplications has been reduced by 3 orders of magnitude relatively to the full VSNE, at the expense of 1.3 dB performance penalty.
