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...
Analysis and Dimensioning of Fully Digital Clock Recovery for 112 Gb/s Coherent Polmux QPSK Systems
Fully Digital Clock Recovery Coherent Polmux QPSK Systems
2015/7/16
Combined effect of polarization mixing and Differential Group Delay (DGD) on sinusoidal and random jitter tolerance is investigated. Requirements for tolerable DGD, loop bandwidth and loop delay are e...
