Intra-Channel Nonlinearity Estimation Based on Statistical Moments Method and Correlation Function
We propose an intra-channel nonlinearity (NL) estimation method for the first time in a 28Gbaud polarization-multiplexed 16 Quadrature Amplitude Modulation (PM-16QAM) system, by correcting high order statistical moments based (HOSMB) optical signal-to-noise ratio (OSNR) estimation method with correlation functions and a calibration factor. Besides, the calibration factor is explored the relationships with transmission distances and channel launched powers. This proposed estimation method is demonstrated to be more accurate than existing estimation methods and functions well in highly nonlinear systems. It has kept estimation errors under 0.8dB with actual OSNR ranging 18-28dB, channel launched power ranging from -4dBm to 4dBm and transmission distances ranging 400-2000km.
