最近，深度学习方法在通信系统中显示出显著的改进。本文研究了非线性信道下的神经网络均衡问题。提出了一种基于神经网络的联合均衡器和译码器，实现了不需要信道状态信息(CSI)的盲均衡和盲译码。与以往的方法不同，我们使用两个神经网络而不是一个。首先，利用卷积神经网络(CNN)自适应地从信道损伤和非线性失真中恢复传输信号。然后深度神经网络解码器(NND)对来自CNN均衡器的检测信号进行解码。实验结果表明，在不同信道条件下，本文提出的CNN均衡器比其他基于机器学习方法的均衡器取得了更好的性能。与最先进的模型相比，所提出的模型减少了约2/3美元的参数。此外，我们的模型可以很容易地应用于复杂度为$\mathcal{O}(n)$的长序列。

英文摘要：
Recently, deep learning methods have shown significant improvements in communication systems. In this paper, we study the equalization problem over the nonlinear channel using neural networks. The joint equalizer and decoder based on neural networks are proposed to realize blind equalization and decoding process without the knowledge of channel state information (CSI). Different from previous methods, we use two neural networks instead of one. First, convolutional neural network (CNN) is used to adaptively recover the transmitted signal from channel impairment and nonlinear distortions. Then the deep neural network decoder (NND) decodes the detected signal from CNN equalizer. Under various channel conditions, the experiment results demonstrate that the proposed CNN equalizer achieves better performance than other solutions based on machine learning methods. The proposed model reduces about $2/3$ of the parameters compared to state-of-the-art counterparts. Besides, our model can be easily applied to long sequence with $\mathcal{O}(n)$ complexity.
