摘要：The nonlinear Fourier transform (NFT) can be used to transmit information overintegrable communication channels such as the optical fiber channel. In this transmissionscheme information is encoded in the nonlinear Fourier transform of the signal, consisting

of two components: a complex discrete and a real continuous spectral function. When thecontinuous spectrum is set to zero, the nonlinear Fourier transform consists only ofdiscrete spectral functions, i.e., N complex numbers in C+ together with the

corresponding N complex spectral amplitudes. In this case, the inverse nonlinear Fouriertransform can be worked out in closed-form, giving rise to N-soliton pulses. Before theINFT for reducing distortion due to the continuous spectrum, spectral component havingan imaginary part near zero are set to zero.
