论文摘要
我们介绍了全双工部门多板毫米波（MMWave）系统的28 GHz自我干扰通道的测量值，例如集成访问和回程。我们测量了传输段阵列面板的输入与共同位置的接收阶段阵列面板的输出之间的隔离，每个阵列面板都以电子方位和高程的多个方向进行电子操作。总共进行了将近650万个测量值，以密集地检查256个元素分阶段阵列之间耦合的方向性。我们观察到，高方向的MMWAVE梁不一定在传输和接收阵列之间提供广泛的高隔离度。相反，我们的测量结果表明，将发射器或接收器转移到其他方面倾向于提供更高的隔离，但即使是轻微的转向变化也会导致隔离的巨大变化。在开发MMWave全双工解决方案时，这些测量值可能是有用的参考，并且可以激发许多未来的主题，包括Beam/用户选择和Beam Forming Codebook Design。
We present measurements of the 28 GHz self-interference channel for full-duplex sectorized multi-panel millimeter wave (mmWave) systems, such as integrated access and backhaul. We measure the isolation between the input of a transmitting phased array panel and the output of a co-located receiving phased array panel, each of which is electronically steered across a number of directions in azimuth and elevation. In total, nearly 6.5 million measurements were taken in an anechoic chamber to densely inspect the directional nature of the coupling between 256-element phased arrays. We observe that highly directional mmWave beams do not necessarily offer widespread high isolation between transmitting and receiving arrays. Rather, our measurements indicate that steering the transmitter or receiver away from the other tends to offer higher isolation but even slight steering changes can lead to drastic variations in isolation. These measurements can be useful references when developing mmWave full-duplex solutions and can motivate a variety of future topics including beam/user selection and beamforming codebook design.
