Residual Carrier-Based Inter-Channel Nonlinearity Compensation for WDM NFDM Systems
Nonlinear frequency division multiplexing (NFDM) exploits the nonlinear Fourier transform (NFT) to modulate signals in the nonlinear spectral domain, where intra-channel Kerr nonlinear distortion can be mitigated. However, inter-channel nonlinear interference remains a major limitation in wavelength division multiplexe...
