Real-time 40-Gbit/s 16-QAM modulation/Demodulation Experiment using a Pilot-Carrier based Phase-Noise Cancelling Technique

Abstract (in Japanese) (See Japanese page) 
(in English) We experimentally demonstrated 40-Gbit/s 16-QAM real-time modulation/demodulation. The phase-noise canceling capability provided by a pilot-carrier and standard electronic pre-equalization (pre-EQ) to suppress inter-symbol interference (ISI) gave clear 16-QAM constellations and eye-diagrams. We observed BER performances of <10-9 using a 200-kHz EC-LD and <10-7 using a 30-MHz DFB-LD.
