Phase noise tolerant carrier recovery scheme for 28 Gbaud circular 16QAM

We propose a novel carrier phase recovery scheme for circular 16QAM coherent transmission systems. Experimental results show low penalties (<;1.4 dB) even for linewidths where square 16QAM exhibits irretrievable (above the FEC limit) error floor.
