LDPC-coded FMF Transmission Employing Unreplicated Successive Interference Cancellation for MDL-Impact Mitigation

A novel MIMO signal processing technique is proposed that successively cancels intermodal crosstalk for MDL-impaired mode-multiplexed signals. Experimental evaluation revealed it provides MDL-tolerance improvement of 3.3 dB and OSNR gain of > 4.5 dB even under a 39ns-DMD FMF link.
