论文摘要
无线研究社区对Sub-Terahertz乐队表示了重大兴趣，该乐队可以在未来的无线网络中实现移动通信。 Sub-Terahertz乐队提供了大量可用的带宽，因此有望以光学速度实现无线通信。在这样的高频带中，收发器需要具有更大的光圈，并且需要比较低的频带更密集地部署。这些因素可以按比例增加远场极限，并且不再忽略电磁波的球形曲率。这为即使在视线频道中也实现空间多路复用的机会。在本文中，我们概述并比较了现有的设计选项，以实现在视线渠道中的高级传输。
The wireless research community has expressed major interest in the sub-terahertz band for enabling mobile communications in future wireless networks. The sub-terahertz band offers a large amount of available bandwidth and, therefore, the promise to realize wireless communications at optical speeds. At such high frequency bands, the transceivers need to have larger apertures and need to be deployed more densely than at lower frequency bands. These factors proportionally increase the far-field limit and the spherical curvature of the electromagnetic waves cannot be ignored anymore. This offers the opportunity to realize spatial multiplexing even in line-of-sight channels. In this paper, we overview and compare existing design options to realize high-rank transmissions in line-of-sight channels.
