摘要:

端到端无线通信是一种新概念,预计将在未来无线通信系统(6G)的物理层中得到广泛应用。它涉及用深度神经网络(DNN)替代发射机和接收机中的模块组件,旨在提高数据传输效率。这将确保自动驾驶车辆(AVs)从自主自治过渡到完全协作自治,而这种协作自治需要具有高数据吞吐量和极低时延的车联网连接。在本文中,我们提出了一种基于Transformer架构的新型神经网络接收机,命名为TransRx,专为车辆到网络(V2N)通信设计。TransRx系统替代了传统通信设置中的常规接收机模块组件。我们在3GPP定义的城市宏蜂窝(UMa)信道上,使用不同的参数集和从0到120 km/h的速度范围,在多种场景下评估了所提出的系统。结果表明,TransRx优于当前最先进的系统,与基于卷积神经网络(CNN)的神经接收机相比,在收敛到低误码率(BER)方面实现了3.5dB的改进;与传统基线接收机配置相比,实现了8dB的改进。此外,我们提出的系统展现出强大的泛化能力,使其适合在大规模环境中部署。

英文摘要:

End-to-end wireless communication is new concept expected to be widely used in the physical layer of future wireless communication systems (6G). It involves the substitution of transmitter and receiver block components with a deep neural network (DNN), aiming to enhance the efficiency of data transmission. This will ensure the transition of autonomous vehicles (AVs) from self-autonomy to full collaborative autonomy, that requires vehicular connectivity with high data throughput and minimal latency. In this article, we propose a novel neural network receiver based on transformer architecture, named TransRx, designed for vehicle-to-network (V2N) communications. The TransRx system replaces conventional receiver block components in traditional communication setups. We evaluated our proposed system across various scenarios using different parameter sets and velocities ranging from 0 to 120 km/h over Urban Macro-cell (UMa) channels as defined by 3GPP. The results demonstrate that TransRx outperforms the state-of-the-art systems, achieving a 3.5dB improvement in convergence to low Bit Error Rate (BER) compared to convolutional neural network (CNN)-based neural receivers, and an 8dB improvement compared to traditional baseline receiver configurations. Furthermore, our proposed system exhibits robust generalization capabilities, making it suitable for deployment in large-scale environments.
