论文摘要
近年来，无线数据流量的扩散使科学界探索了较高的未分配频带的使用，例如毫米波和Terahertz（0.1-10 THZ）频段。但是，它们很容易遇到收发器路径中的障碍物的阻塞。为了解决这一问题，在这项工作中，研究了在D波段（110-170 GHz）运行的发射机（TX）和接收器（RX）之间恢复发射机（TX）和接收器（RX）之间的链接的使用。考虑RIS设计参数，TX/RX-RIS距离以及从RIS中心到收发器的高程角度，对系统性能进行了评估。
In the recent years, the proliferation of wireless data traffic has led the scientific community to explore the use of higher unallocated frequency bands, such as the millimeter wave and terahertz (0.1-10 THz) bands. However, they are prone to blockages from obstacles laid in the transceiver path. To address this, in this work, the use of a reconfigurable-intelligent-surface (RIS) to restore the link between a transmitter (TX) and a receiver (RX), operating in the D-band (110-170 GHz) is investigated. The system performance is evaluated in terms of pathgain and capacity considering the RIS design parameters, the TX/RX-RIS distance and the elevation angles from the center of the RIS to the transceivers.
