Low-complexity cluster-assisting look-up-table-based Volterra decision-feedback equalizer for IM/DD systems
To address the challenges posed by chromatic dispersion (CD)-induced power fading and nonlinear signal distortions in double-sideband (DSB) intensity modulation and direct detection (IM/DD) transmission systems, a combination of a Volterra feed-forward equalizer (VFFE) and a Volterra decision-feedback equalizer (VDFE) is widely employed. However, the conventional VFFE–VDFE exhibits significant computational complexity, particularly for longer memory lengths.

Nonlinearity-aware PS-PAM-16 transmission for C-band net-300-Gbit/s/λ short-reach optical interconnects with a single DAC
Abstract A nonlinearity-aware signal transmission scheme based on a low-complexity 3rd-order diagonally pruned absolute-term nonlinear equalizer (NLE) with weight sharing (DP-AT-NLE-WS) and rate-adaptable probabilistically shaped 16-level pulse amplitude modulation (PS-PAM-16) signal is proposed and experimentally demonstrated for C-band net-300-Gbit/s/λ short-reach optical interconnects.
