Does the Cross-Talk Between Nonlinear Modes Limit the Performance of NFDM Systems? (1801.00159v1)
Published 30 Dec 2017 in eess.SP, cs.IT, and math.IT
Abstract: We show a non-negligible cross-talk between nonlinear modes in Nonlinear Frequency-Division Multiplexed system when data is modulated over the nonlinear Fourier spectrum, both the continuous spectrum and the discrete spectrum, and transmitted over a lumped amplified fiber link. We evaluate the performance loss if the cross-talks are neglected.
