Low-Complexity, Blind Phase Recovery for Coherent Receivers Using QAM Modulation
Low-Complexity Blind Phase Recovery Coherent Receivers QAM Modulation
2011/5/20
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...
XPM Tolerant Adaptive Carrier Phase Recovery for Coherent Receiver Based on Phase Noise Statistics Monitoring
XPM Tolerant Adaptive Carrier Phase Recovery Coherent Receiver Phase Noise Statistics
2009/7/17
According to the monitored phase noise statistics, the averaging weights in carrier phase recovery is adaptively optimized. Comparing with existing optimization techniques, 1dB Q value improvement can...
