A Study on Residual Distortion Equalization in Combination with Pre-distortion and Post-equalization

Not Accessible

Abstract

We show numerically that in a 40Gb/s-QPSK system, dispersion incompletely compensated by pre-distortion can be precisely equalized by a post-equalizer. The compensation capability is strongly dependent on the demodulation scheme, i.e. coherent or incoherent.
