Single-carrier 448 Gb/s dual-polarization 16-QAM transmission over 1200 km using fixed look-up table based MAP detection

Transmission of a single-carrier 448 Gb/s dual-polarization 16-QAM signal is demonstrated using fixed look-up table based maximum-a-posteriori detection at the receiver to mitigate pattern-dependent distortion in the transmitted signal arising from the high baud rate.
