Experimental demonstration of decision-aided maximum likelihood phase estimation in 8-Channel 42.8-Gbit/s DWDM coherent PolMux-QPSK system

We experimentally demonstrate a novel decision-aided maximum likelihood phase estimation in an 8-Channel 42.8-Gbit/s DWDM coherent PolMux QPSK system. The results show that our proposed algorithm can achieve a comparable performance as the Mth-power while having much lower computational complexity.
