Abstract :
We demonstrate the first digital laser-phase-noise (PN) mitigation approach for DDO-OFDM which applies a simple Wiener filter for adaptively estimating the statistical-unknown PN. The PN tolerance, in terms of the achievable fibre length, is about tripled with this PN mitigation technique.
