A Effective Carrier Phase Recovery Method in Tigth Time-Packing Fast than Nyquist Optical Communication System

A Effective Carrier Phase Recovery Method in Tigth Time-Packing Fast than Nyquist Optical Communication System

We propose a new scheme that combines polybinary transformaton and corrected-BPS to compensate noise for PDM-FTN-QPSK when its accelerated factor is 0.5,which has 3.3 dB OSNR gain when phase noise is 800 kHz.
