Abstract

Software-Defined Metasurfaces (SDMs) have ad-vanced from basic theoretical ideas to a key enabler for next generation wireless systems. When massively deployed in a wireless environment, they can realize precise, software-defined propagation of signals and wireless channel customizations. A plethora of studies have thoroughly investigated the physical design of the SDMs and their wireless channel engineering capa-bilities. This work introduces a novel architecture and associated processes for integrating SDMs into existing networked wireless systems. First, the integration architecture and the according complex underlying physics of the SDMs are presented. Then the software abstractions are proposed that enable the interaction of the surfaces in a physics-agnostic manner. These software abstractions require an SDM profile to operate in real-time, i.e., a database that accurately describes the capabilities of a given metasurface. Thus, the manufacturing time workflows are suggested to produce such a profile. The proposed solutions are evaluated in an actual physical setup/testbed.

将软件定义的元表面集成到无线通信系统:设计和原型评估

软件定义元表面(sdm)已经从基本的理论思想发展成为下一代无线系统的关键推动者。当大规模部署在无线环境中时，它们可以实现精确的、软件定义的信号传播和无线信道定制。大量的研究已经彻底调查了sdm的物理设计及其无线信道工程能力。这项工作介绍了一种将sdm集成到现有网络无线系统中的新架构和相关流程。首先，介绍了sdm的集成体系结构和相应的复杂底层物理。然后提出了软件抽象，使表面的相互作用以一种物理不可知的方式。这些软件抽象需要一个实时操作的SDM配置文件，也就是说，一个准确描述给定元表面功能的数据库。因此，建议制造时间工作流生成这样一个概要文件。提出的解决方案在实际的物理设置/测试平台中进行了评估。
