Abstract

Wireless networks are undergoing a transformative shift, driven by the crucial factors of cost-effectiveness and sustainability. Digital coding metasurfaces (DCMs) might play a key role in realizing cost-effective digital modulators by harnessing energy embedded in electromagnetic waves traversing through the air. Integrated sensing and communication (ISAC) optimizes power and spectral resources by combining sensing and communication functionalities on a shared hardware platform. This article presents a tutorial-style overview of the applications and advantages of DCMs in ISAC-based networks. Emphasis is placed on the dual functionality of ISAC, necessitating the design of DCMs with simultaneously transmitting and reflecting (STAR) capabilities for comprehensive space control. Additionally, the article explores key signal processing challenges and outlines future research directions stemming from the convergence of ISAC and emerging STAR-DCM technologies.

传感与通信一体化：同时发射和反射数字编码元表面：物理学与信号处理的成功融合[综合传感与通信革命的信号处理特刊］

在成本效益和可持续性等关键因素的推动下，无线网络正在经历一场变革。数字编码元表面（DCM）可以利用穿越空气的电磁波中蕴含的能量，在实现具有成本效益的数字调制器方面发挥关键作用。集成传感和通信（ISAC）通过在共享硬件平台上结合传感和通信功能，优化了功率和频谱资源。本文以教程的形式概述了 DCM 在基于 ISAC 的网络中的应用和优势。文章重点介绍了 ISAC 的双重功能，这就需要设计具有同时发射和反射 (STAR) 功能的 DCM，以实现全面的空间控制。此外，文章还探讨了信号处理方面的主要挑战，并概述了 ISAC 与新兴 STAR-DCM 技术融合后的未来研究方向。
