“…Some methods to compensate for nonlinear effects in wireless communication systems have been studied with NNs [4,5]. In optical communication systems, nonlinear distortion compensation using NNs has been conventionally studied for Intensity Modulation-Direct Detection (IM-DD) transmission systems [6,7]. Recently, nonlinear equalization using NNs in frequency domain was investigated for coherent optical orthogonal frequency division multiplexing (CO-OFDM) transmission systems, where many sub-NNs were used for subcarriers [8,9].…”

We experimentally demonstrated a novel nonlinearity mitigation scheme based on digital signal processing using a three-layer neural network (NN). 40-Gbit/s optical 16QAM signal distorted by SPM was compensated, improving EVM values by about 15%. We also performed numerical simulation of the proposed scheme, and confirmed that the experiment agrees with the results of the simulation. We performed 100 times of learning processes to find weight and bias of each neuron. However, we did not observe any serious local minimum. We also investigated the effect of the number of neurons of the NN on the compensation performance.

We studied a novel nonlinear compensation scheme using digital signal processing based on a neural network (NN). Distortion of 16QAM signals caused by self-phase modulation (SPM) was compensated for by using a three-layer NN without feedback loops. In the scheme, the input layer of the NN has feedforward tapped delay lines. Input signals of I and Q components of the 16QAM signals are fed into the delay lines. The compensated 16QAM signals of the I and Q components are outputted by two neurons in the output layer of the NN. BER and EVM performance was investigated by numerical simulations, and the EVM was improved by more than 20% by the compensation.
