本文提出了一种由毫米波（mmWave）动态超表面天线（DMA）实现的实时60GHz无线视频传输系统，提供了一种60GHz收发器解决方案。该端到端通信系统采用商用毫米波上/下变频模块（EK1HMC6350、HMC6300和HMC6301）、带连接器的基于DMA的发射前端，以及用于数字基带处理的通用软件无线电外设（USRP）搭建而成。所提出的框架无需昂贵的高频信号发生器和频谱分析仪，从而简化了实现与验证过程，同时降低了运营成本。采用QPSK调制方式，在无线链路上成功传输并恢复了720p分辨率（1280×720）的实时高清视频流，数据速率约为3Mbps，可靠性高。所演示的平台可支持多种60GHz标准物理层协议，如IEEE 802.11ad/ay和802.15.3c。本研究凸显了可编程超表面天线作为紧凑、高能效的替代方案，在下一代6G及后续毫米波/太赫兹无线通信系统、小小区户外回传链路以及射频嗅探与信道探测中，相较于传统相控阵天线的应用潜力。
英文摘要
This paper presents a real-time 60 GHz wireless video transmission system enabled by a millimeter-wave (mmWave) Dynamic Metasurface Antenna (DMA) and offers a 60 GHz transceiver solution. The end-to-end communication system is established using off-the-shelf mmWave up/down-conversion modules (EK1HMC6350, HMC6300, and HMC6301) with a connectorized DMA-based transmit front-end and universal software radio peripheral (USRP) for digital baseband processing. The proposed framework eliminates the need for costly high-frequency signal generators and spectrum analyzers, thus simplifying implementation and validation while reducing operational costs. A real-time HD video stream at 720p resolution (1280 x 720) is transmitted and successfully retrieved over a wireless link using QPSK modulation, achieving a data rate of about 3 Mbps with high reliability. The demonstrated platform can support various 60 GHz standard physical-layer protocols, such as IEEE 802.11ad/ay and 802.15.3c. This work highlights the potential of programmable metasurface antennas as a compact, energy-efficient alternative to legacy phased arrays for next-generation 6G and beyond mmWave/sub-THz wireless communication systems, small-cell outdoor backhaul links, and RF sniffing and channel sounding.
