Delay-Tap-Sampling-Based Chromatic Dispersion Estimation Method With Ultra-Low Sampling Rate for Optical Fiber Communication Systems

IEEE Access, 2020
A cost-effective chromatic dispersion (CD) estimation method is proposed, which is based on the delay-tap sampling (DTS) technique in combination with periodic training sequences (PTS). By performing equivalent sampling of PTS, DTS-based CD estimation at
