A Low Complexity Pre-Distortion Method for Intra-channel Nonlinearity
Low Complexity Pre-Distortion Method Intra-channel Nonlinearity
2015/5/21
We propose a low complexity intra-channel nonlinearity pre-distortion method based on symbol rate operation. The method is experimentally verified under a 43Gb/s DP-QPSK coherent system, and the perfo...
On the efficiency of RF-Pilot-based nonlinearity compensation for CO-OFDM
efficiency RF-Pilot-based nonlinearity compensation CO-OFDM
2015/5/21
We investigate the efficiency of RF-pilot based phase noise compensation for mitigation of nonlinear impairments in CO-OFDM transmission. We show that the efficiency scales with the effective dispersi...
Experimental Characterization of Nonlinearity Mitigation by Digital Back Propagation and Nonlinear Polarization Crosstalk Canceller under High PMD condition
High PMD condition Digital Back Propagation Nonlinear Polarization Crosstalk Canceller
2015/5/15
Impact of PMD is evaluated on nonlinear mitigation algorithm. While the backpropagation showed consistent improvement regardless of PMD, the best performance was found under different PMD conditions d...
