Advanced equalizer for 800-Gb/s DP-16QAM coherent transmission systems.
In this paper, we propose an advanced equalization scheme by cascading a feed-forward equalizer (FFE)-based 2 × 2 MIMO with a simplified soft-output maximum likelihood sequence estimation (s-SMLSE) for high-speed coherent optical communication systems. The first-stage FFE mitigates the inter-symbol interference (ISI) r...
