Pulse shaping in the nonlinear Fourier domain

In recent years, many new fiber-optic transmission schemes based on nonlinear Fourier transforms (NFT) have been proposed. The time domain characteristics of the pulses generated by these schemes can differ significantly. Pulse shapes have a considerable impact on spectral efficiency. We therefore survey existing NFT-based transmission schemes in this talk, and discuss the different possibilities to control the pulse shapes that they offer.
