在通信技术中，可编程超表面（PM）是一种很有前途的天线阵列概念，可以克服毫米波（mmW）频率下严重的路径损耗。它通过使用普通馈电天线实现电子可操纵波束形成，而不需要像传统的多输入多输出（MIMO）和相控阵结构那样的平行射频（RF）链。这些优势使PM有机会成为未来通信发展的一部分。在这项工作中，提出了一种使用工作在28ghz的PM的新型通信系统。为了验证系统的性能，实现了通信信号传输和穷举信道估计算法。实测结果表明，系统性能良好，与理论结果吻合较好。
In communication technology, a programmable metasurface (PM) is a promising antenna array concept to overcome the severe path loss at millimeter-wave (mmW) frequencies. It enables electronically steerable beamforming by using a normal feeding antenna without the need of parallel radio frequency (RF) chains as conventional multiple input multiple output (MIMO) and phased array structures. These advantages offer PM the chance to be a part of future communication developments. In this work, a novel communication system using a PM operating at 28 GHz is presented. In order to prove the system performance, communication signal transmission as well as an exhaustive channel estimation algorithm have been implemented. The measurement results show great system performances, which nicely match with theoretic results.
