We present a blind dispersion estimation algorithm for adaptive equalizers, suitable for
uncompensated transmission and able to precisely estimate arbitrary large dispersion at a
fixed adaptation length and low complexity. The presented solution is validated for coherent
polarization multiplexed (CP) (NRZ/RZ)-QPSK. …

Abstract
Blind adaptive chromatic dispersion equalization for coherent polarization multiplexed (NRZ/RZ)-QPSK receivers is presented. A novel low complexity estimation algorithm precisely estimates arbitrarily large dispersion in a fixed adaptation length.
