摘　　要：通信感知一体化(ISAC)需要通信和感知共用无线电频段和硬件资源。多频段、大带宽、通信感知对硬件的要求不同等特点对通信感知一体化硬件设计提出更高要求。该文对后5G,6G,WiFi等通信感知一体化的硬件设计、验证技术,以及硬件系统性验证平台进行归纳,对国内外近年相关硬件设计研究及其验证情况进行综述,关注通信感知两种系统对硬件的需求矛盾、带内全双工(IBFD)自干扰消除(SIC)、功放(PA)效率、电路性能对建模要求更高等硬件设计挑战。首先,总结、比较已有研究中通信感知一体化收发信机架构设计。然后,介绍、分析现有通信感知一体化带内全双工自干扰抑制方案、低峰均功率比(PAPR)波形与高性能PA设计、器件高精度建模方法以及硬件系统性验证平台。最后,总结全文并对未来通信感知一体化硬件设计所面临的开放性问题进行展望。Objective:The field of cellular mobile communication is advancing toward post-5G(5.5G,Beyond 5G,5G Advanced)and 6th Generation(6G)standards.This evolution involves a shift from traditional sub-6 GHz operating frequency bands to higher frequency ranges,including millimeter wave(mmWave),terahertz(THz),and even visible light frequencies,which intersect with radar operating bands.Technologies such as Orthogonal Frequency Division Multiplexing(OFDM)and Multiple Input Multiple Output(MIMO)have gained widespread application in both wireless communication and radar domains.Given the shared characteristics and commonalities in signal processing and operating frequency bands between these two fields,“Integrated Sensing And Communication(ISAC)”has emerged as a significant research focus in wireless technologies like 5G Advanced(5G-A),6G,Wireless Fidelity(WiFi),and radar.This development points toward a network perception paradigm that combines communication,sensing,and computing.The“ISAC”concept aims to unify wireless communication systems(including cellular and WiFi)with wireless sensing technologies(such as radar)and even network Artificial Intelligence(AI)computing capabilities into a cohesive framework.By integrating these elements,the physical layer can share frequencies and Radio Frequency(RF)hardware resources,leading to several advantages:spectrum conservation,cost reduction,minimized hardware size and weight,and enhanced communication perception.In this article,the focus of communication perception integration is primarily on radar communication.ISAC necessitates that both communication and sensing utilize the same radio frequency band and hardware resources.The diverse characteristics of multiple frequency bands,along with the varying hardware requirements for communication and sensing,present increased challenges for ISAC hardware design.Effective hardware design for ISAC systems demands a well-considered architecture and device design for RF transceivers.Key considerations include the receiver’s contin
