摘　　要：通感一体化在学术界和产业界都引起了广泛的关注和研究热潮,并被国际电信联盟ITU确定为6G的六大应用场景之一。在通信系统中引入感知功能时,由器件的非理想性引起的一些问题对于感知性能有着决定性的影响,称之为感知非理想因素。将从感知非理想因素的背景入手,进而分析四项感知非理想因素对于感知性能的影响。对于部分感知非理想因素,梳理了几种消除方法及其原理。最后,通过仿真或样机测试的方法,直观地展示了感知非理想因素的影响。特别地,在样机测试中,通过参考径方法进行感知非理想因素的消除,获取较好的效果。Integrated sensing and communication has attracted significant attention and research focus in both academia and industry,earning recognition as one of the six fundamental application scenarios for 6G by the International Telecommunication Union.However,the introduction of sensing capabilities into communication systems presents challenges arising from non-idealities of sensing devices,which can significantly affect sensing performance,known as sensing non-ideal factors.This paper begins by providing an overview of the background of sensing non-ideal factors,followed by a thorough analysis of the impact of four specific sensing non-ideal factors on sensing performance.For some of these factors,various elimination methods and their underlying principles are examined.Finally,the influence of sensing non-ideal factors is visually demonstrated by simulation or prototype testing.Notably,in prototype testing,promising results are achieved through the application of reference channel methods to eliminate sensing non-ideal factors.
