Cycle Slip Mitigation in POLMUX-QPSK Modulation
Cycle Slip Mitigation POLMUX-QPSK Modulation
2015/5/20
We demonstrate a pilot-symbol assisted joint polarization carrier phase estimation technique that detects cycle slip and avoid error propagation. Coherent detection without differential coding is feas...
Nonlinear Phase Noise Mitigation by Polarization Mode Dispersion in Dispersion Managed coherent PDM-QPSK Systems
Nonlinear Phase Noise Mitigation Polarization Mode Dispersion Dispersion Managed coherent PDM-QPSK Systems
2015/7/17
We show by simulation that PMD helps reduce nonlinear phase noise in single-channel coherent PDM-QPSK systems at both 43 and 112 Gbit/s, with improved resilience at 112 Gbit/s.
Fiber Nonlinearity Mitigation by PAPR Reduction in Coherent Optical OFDM Systems via Active Constellation Extension
Fiber Nonlinearity PAPR Optical OFDM Systems Active Constellation Extension
2015/8/4
We consider Active Constellation Extension to reduce the PAPR in CO-OFDM systems. We find that the nonlinearity threshold is improved by 1.5 dB at a reach of 400 km SSMF fiber.
