Abstract :
We confirm backward-propagation nonlinear compensation makes noise statistics after nonlinear transmission closer to Gaussian and recovers the performance of low-density parity-check (LDPC) code with superchannel signal that consists of densely packed 5 × 34-GBd Nyquist dual-polarization 16QAM.
