论文摘要
实现超级可靠，低延迟和安全的通信对于实现工业互联网（IIT）至关重要。非固定的大量多输入多输出（MIMO）是满足超可靠和低延迟要求的有前途的技术之一。此外，由于其低延迟属性，物理层身份验证（PLA）技术特别适合安全IIOT通信。本文提出了用于非连通大量单输出多出输出（SIMO）IIOT通信系统的PLA方法。此方法通过将身份验证信号（TAG）嵌入到消息信号中，称为“基于消息的标签嵌入”来实现PLA。它与使用统一功率标签的传统PLA方法不同。我们设计最佳标签嵌入并优化消息和标签信号之间的功率分配，以表征消息和标签错误性能之间的权衡。数值结果表明，所提出的基于消息的标签嵌入PLA方法比传统的统一标签嵌入方法更准确，该方法的标签误差接近10％。
Achieving ultra-reliable, low-latency and secure communications is essential for realizing the industrial Internet of Things (IIoT). Non-coherent massive multiple-input multiple-output (MIMO) is one of promising techniques to fulfill ultra-reliable and low-latency requirements. In addition, physical layer authentication (PLA) technology is particularly suitable for secure IIoT communications thanks to its low-latency attribute. A PLA method for non-coherent massive single-input multiple-output (SIMO) IIoT communication systems is proposed in this paper. This method realizes PLA by embedding an authentication signal (tag) into a message signal, referred to as "message-based tag embedding". It is different from traditional PLA methods utilizing uniform power tags. We design the optimal tag embedding and optimize the power allocation between the message and tag signals to characterize the trade-off between the message and tag error performance. Numerical results show that the proposed message-based tag embedding PLA method is more accurate than the traditional uniform tag embedding method which has an unavoidable tag error floor close to 10%.
