Abstract: We propose a low-complexity cluster-pruning look-up-table-based Volterra decision-feedback equalizer (CPLUT-VDFE) to substantially reduce the computational complexity associated with compensating for chromatic dispersion (CD) and nonlinear distortions in intensity modulation and direct detection (IM/DD) transmission systems.… read more here.

Abstract: To cope with the nonlinear distortions and the chromatic dispersion (CD) induced power fading in double-side band (DSB) intensity modulation and direct detection (IM/DD) transmission systems, high-performance Volterra nonlinear equalizers (VNLEs) including Volterra feed-forward equalizer… read more here.
