Equalizer complexity of mode division multiplexed coherent receivers

We show that OFDM requires the lowest equalizer complexity for crosstalk compensation in a mode-division-multiplexing receiver. For a 2000-km transmission distance and less than 10% OFDM-specific overhead, the modal dispersion must be below 12 ps/km.
