针对AWGN信道设计的传统软解映射器在实际信道下会有性能损失。我们提出了一个神经网络的软解映射器,并显示在800 Gb/s的相干传输实验中使用DP-32 QAM的增益为0.35dB。
Conventional soft demappers designed for AWGN channels suffer from performance loss under realistic channels. We propose a neural network soft demapper and show a gain of 0.35dB in an 800Gb/s coherent transmission experiment using DP-32QAM.
