Query: Experimental validation of MDL emulation and estimation techniques for
  SDM transmission systems   We experimentally validate a mode-dependent loss (MDL) estimation technique
employing acorrection factor to remove the MDL estimation dependence on the SNR
when using a minimum meansquare error (MMSE) equalizer. A reduction of the MDL
estimation error is observed for both transmitter-side and in-span MDL
emulation.
