Low-Complexity, Blind Phase Recovery for Coherent Receivers Using QAM Modulation
Low-Complexity Blind Phase Recovery Coherent Receivers QAM Modulation
2015/5/20
We propose a new hybrid PLL/ML phase estimation method for low-complexity, blind phase recovery for M-QAM modulation. The linewidth tolerance of the proposed method is more than one order of magnitude...
Transmission of 5x62 Gbit/s DWDM Coherent OFDM with a Spectral Efficiency of 7.2 Bit/s/Hz using Joint 64-QAM and 16-QAM Modulation
Modulation Coherent communications
2015/6/8
Transmission of 5x62 Gbit/s polarization multiplexed coherent OFDM is demonstrated over 80 km SSMF. Using 64-QAM and 16-QAM simultaneously allows reducing the channel spacing and makes a net spectral ...
240-Gb/s Polarization-Multiplexed 64-QAM Modulation and Blind Detection Using PLC-LN Hybrid Integrated Modulator and Digital Coherent Receiver
Polarization-Multiplexed 64-QAM Modulation Blind Detection PLC-LN Hybrid Integrated Modulator Digital Coherent Receiver
2015/7/20
We demonstrate 240-Gb/s 64-QAM signal modulation and detection. 20-Gbaud 64-QAM signals are generated employing hybrid integration of silica PLCs and LiNbO 3 phase modulators, and demodulated with a d...
