Equalization-enhanced phase noise in mode-division multiplexed systems

Abstract

When an electronic equalizer is used to compensate the modal dispersion in a mode-division multiplexed system, receiver phase noise induces interference to the multi-input-multi-output (MIMO) receiver. Based on the statistics of the modal dispersion in the strong coupling regime, the interference variance is evaluated analytically based on an exact model, a semicircle asymptotic for large number of modes, and a first-order approximation. © 1983-2012 IEEE.
