The joint communication and sensing (JCAS) technology is considered as a promising technology for solving the spectrum congestion problem in next generation of wireless networks and beyond, where the communication and radar system will be integrated in one hardware platform and operate simultaneously over the same frequency. The overarching goal of the DFRC-DESIGNproject is to design, analyze and validate innovative JCAS systems capable of achieving improved spectrum efficiency. To have a better trade-off performance between communication and sensing functionalities compared to the existing systems, we will make aparadigm shift in the design principles of the system from the existing principle of realizing a second function based on the primaryfunction of the system to the joint design principle that considers both functions simultaneously. To achieve this, the following challenges arise in our design: i) How to define the performance metrics of JCAS? ii) How to design waveforms that satisfy the properties required for both communication and sensing? iii) How to exploit the spatial characteristics of the beam in a MIMO system to simultaneously detect targets and serve users in different orientations? iv) How to tackle the clutter signal for robust and highaccuracy sensing? v) How much performance gain can the JCAS system achieve for both functions in realistic situations? In this project, a theoretical analysis framework, novel waveform design, hybrid beamforming algorithms, clutter suppression and parameterestimation procedures will be proposed to address these issues, using optimization theory, statistical signal processing and deeplearning techniques. Furthermore, a testbed will be set up under realistic settings to demonstrate the proposed schemes. The results will be disseminated to the public through several communication activities to improve public awareness of milimeter waves and to promote mutual understanding and sustainable development.

联合通信和传感（JCAS）技术被认为是解决下一代无线网络及其他地区的光谱拥塞问题的有前途的技术，在该技术中，通信和雷达系统将集成到一个硬件平台中并同时以相同的频率进行操作。 DFRC-DesignProject的总体目标是设计，分析和验证能够提高频谱效率的创新JCAS系统。与现有系统相比，为了在通信和传感功能之间具有更好的权衡性能，我们将使系统的设计原理从现有原理中转移基于系统的主要功能到同时考虑这两种功能的关节设计原理的第二个功能。为了实现这一目标，我们的设计中会出现以下挑战：i）如何定义JCAS的性能指标？ ii）如何设计满足通信和传感所需属性的波形？ iii）如何利用MIMO系统中光束的空间特性以同时检测目标并以不同方向为用户服务？ iv）如何​​应对杂乱无章的信号以进行稳健和高精度感应？ v）在现实情况下，JCAS系统可以为这两个功能实现多少性能增益？在这个项目中，将提出一个理论分析框架，新型波形设计，混合波束形成算法，混乱抑制和参数估计程序，使用优化理论，统计信号处理和深度学习技术来解决这些问题。此外，将在现实设置下设置测试台以证明所提出的方案。结果将通过几项沟通活动将其传播给公众，以提高公众对米仪浪潮的认识，并促进相互理解和可持续发展。
