We propose a transceiver-impairment-tolerant 4D×D multiple-input/multiple-output equalizer with significantly reduced computational overhead and improved tracking performance for spatial-division-multiplexed receivers and demonstrated it in a 100-Gbaud transmission over a cabled four-coupled-core transmission line with MHz-class fluctuation.
