Misaligned optic carrier polarization division multiplexing SSB-OOFDM system based on a beat interference cancellation receiver

Polarization Multiplexed Optical OFDM System With a Beat Interference Cancellation Receiver

“…Several beat interference cancellation techniques specifically for PDM SSB-OOFDM systems with reduced GB have been proposed to eliminate SSBIs in [26,27]. In 2019, we have proposed a misaligned optical carrier (MOC) PDM SSB-OOFDM system based on a single BICR to avoid the PMD [28], but the SE is low since the misaligned OCs at the same sideband leave a blank spectrum gap. Recently, Canadian scholars proposed an asymmetric direct detection (ADD) for canceling the SSBI in the PDM SSB-OOFDM system with orthogonal offset carriers [29].…”
