Time-Domain Adaptive Decision-Directed Channel Equalizer for RGI-DP-CO-OFDM

We propose an efficient time-domain adaptive decision-directed channel equalizer (TD-ADDCE) for reduced-guard-interval dual-polarization coherent optical orthogonal frequency-division-multiplexing (RGI-DP-CO-OFDM) transmission systems. TD-ADDCE estimates the phase noise in a decision-directed scheme by extracting and averaging the phase drift of OFDM… CONTINUE READING
