论文摘要
这封信建议使用智能反射表面（IRS）作为信息媒体，以显示微波快速响应（QR）代码，以适用于本互联网应用程序。具体来说，由于其可调元素，IRS用于形成动态位图图像。在IRS上显示的QR码后，共同设计传输和接收天线阵列，以通过辐射电磁波以及接收和检测反射信号来扫描它。基于这样的想法，对IRS启用信息和通信系统进行了建模。因此，研究了一些基本的系统操作机制，涉及信号调制的平均位误差概率，IRS上的QR码实现，传输设计，检测等。执行模拟以显示系统的可实现通信性能并确认IRS基于IRS的Microwave QR码的可行性。
This letter proposes to employ intelligent reflecting surface (IRS) as an information media to display a microwave quick response (QR) code for Internet-of-Things applications. To be specific, an IRS is used to form a dynamic bitmap image thanks to its tunable elements. With a QR code shown on the IRS, the transmitting and receiving antenna arrays are jointly designed to scan it by radiating electromagnetic wave as well as receiving and detecting the reflected signal. Based on such an idea, an IRS enabled information and communication system is modelled. Accordingly, some fundamental systematic operating mechanisms are investigated, involving derivation of average bit error probability for signal modulation, QR code implementation on an IRS, transmission design, detection, etc. The simulations are performed to show the achievable communication performance of system and confirm the feasibility of IRS-based microwave QR code.
