项目摘要

Sensing is envisioned as an indispensable part to construct an intelligent in-building environment. Compared to well-developed wireless communications, radio/radar sensing is still in its infancy for indoor networks. As 5G and beyond wireless networks will be ubiquitous indoors, it is particularly attractive to realise extra sensing capability that is piggybacked on indoor wireless networks.Recent developments in dual-functional radar-communication (DFRC) systems represent an excellent opportunity to integrate wireless communications and radar sensing indoors. For an indoor DFRC system, its communication and sensing (C&S) performance largely depends on the DFRC transceiver and the radio environment. Even though major efforts have been made on designing DFRC transceivers, radio environments as another key element to realise the potential of DFRC for integrated C&S remain unexplored. To realise the potential of DFRC systems for integrated C&S, the CIRED project will: 1) Define a set of metrics to measure the C&S performance of indoor radio environments; 2) Establish mathematical models to characterise the impact of indoor radio environments on DFRC systems; and 3) Develop advanced algorithms to optimally customise indoor radio environments for C&S. The achievement of these objectives will significantly enhance the C&S performance of indoor DFRC systems. The project is timely as integrated sensing and communication (ISAC) is critical for 6G networks.

感知被认为是构建智能建筑内环境不可或缺的一部分。与成熟的无线通信相比，无线电/雷达传感在室内网络中还处于起步阶段。由于5G及以上的无线网络将在室内无处不在，因此实现搭载在室内无线网络上的额外侦听能力尤其具有吸引力。最近双功能雷达通信(DFRC)系统的发展为室内集成无线通信和雷达侦听提供了一个极好的机会。对于室内DFRC系统，其通信和感知(C&S)的性能在很大程度上取决于DFRC收发信机和无线电环境。尽管DFRC收发机的设计已经做出了很大努力，但作为实现DFRC集成C&S潜力的另一个关键因素，无线电环境仍未得到探索。为了实现分布式FRC系统在集成C&S系统中的潜力，Cired项目将：1)定义一套衡量室内无线电环境C&S性能的指标；2)建立数学模型来表征室内无线电环境对DFRC系统的影响；以及3)开发高级算法来优化定制C&S室内无线电环境。这些目标的实现将显著提高室内DFRC系统的C&S性能。该项目非常及时，因为集成传感和通信(ISAC)对6G网络至关重要。
