摘要:

现实的自由空间光通信系统受到光通过大气的湍流传播和接收器处的检测器噪声的影响,这会显著降低接收状态的光模式质量,增加模式之间的串扰,并且相应地增加系统的符号错误率(SER)。为了克服这些障碍,我们开发了一个最先进的生成机器学习(GML)和卷积神经网络(CNN)系统相结合,并证明其在自由空间光(FSO)通信设置的有效性。该系统可校正湍流引起的失真效应并降低检测器噪声,从而显着降低接收器输出端的SERS和串扰,同时无需反馈。该方案易于扩展,并且可以在不久的将来为建立远程经典和量子通信链路提供具体且具有成本效益的技术。

英文摘要:

Realistic free-space optical communications systems suffer from turbulent propagation of light through the atmosphere and detector noise at the receiver, which can significantly degrade the optical mode quality of the received state, increase cross-talk between modes, and correspondingly increase the symbol error ratio (SER) of the system. In order to overcome these obstacles, we develop a state-of-the-art generative machine learning (GML) and convolutional neural network (CNN) system in combination, and demonstrate its efficacy in a free-space optical (FSO) communications setting. The system corrects for the distortion effects due to turbulence and reduces detector noise, resulting in significantly lowered SERs and cross-talk at the output of the receiver, while requiring no feedback. This scheme is straightforward to scale, and may provide a concrete and cost effective technique to establishing long range classical and quantum communication links in the near future.
