Abstract

Multiple-input multiple-output (MIMO) technology, a core component of 6G, has been widely adopted in optical wireless communication (OWC) systems. Accurate recognition of different MIMO types is essential for MIMO selection and demodulation. In this Letter, we propose an open-set MIMO recognition method for OWC systems using a Siamese neural network (SNN). Simulation results show that the SNN significantly outperforms other recognition approaches, including convolutional neural networks (CNNs) and traditional machine learning techniques. For SNN-based recognition, over 90% accuracy is achieved with training based on only nine fixed sampling points in both 2 × 2 and 4 × 4 MIMO-OWC systems.

基于Siamese神经网络的OWC智能开集MIMO识别。

多输入多输出（MIMO）技术是6G技术的核心组成部分，在光通信系统中得到了广泛的应用。准确识别不同的MIMO类型是MIMO选择和解调的关键。在本文中，我们提出了一种基于Siamese神经网络（SNN）的开放集MIMO识别方法。仿真结果表明，SNN显著优于其他识别方法，包括卷积神经网络（cnn）和传统的机器学习技术。对于基于snn的识别，在2 × 2和4 × 4 MIMO-OWC系统中，仅基于9个固定采样点的训练就可以达到90%以上的准确率。

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
