在MmWave Wi-Fi中,传感与通信的集成程度如何?

How Well Sensing Integrates with Communications in MmWave Wi-Fi?

Mohamed Abdalgader, Nadia Adem

摘要:

通感一体化(ISAC)系统的发展最近因其提供包括资源共享和新应用(例如,定位、跟踪和健康护理相关)的各种服务的能力而引起了人们的兴趣。虽然通过许多技术提供了感测能力,但归因于它们的广泛部署以及它们提供的高频谱和高范围分辨率,其通过Wi-Fi网络IEEE 802.11ad和802.11ay的可访问性已经引起了研究和工业的兴趣。尽管有一个专门的标准化机构,即802.11bf任务组,致力于提高Wi-Fi传感性能,但仍需要进行调查以评估各种传感技术的有效性。在这个项目中,我们,除了调查相关文献,我们评估的毫米波(毫米波)的Wi-Fi系统的传感性能,通过使用Matlab仿真工具模拟一个场景的人体目标。在该分析中,我们使用短时傅里叶变换(STFT)来处理信道估计数据。此外,使用信道变化阈值的方法,我们评估的性能,同时减少反馈。我们的研究结果表明,使用STFT窗口重叠可以提供良好的跟踪结果,并且使用0.05和0.1阈值水平的反馈测量的减少分别减少了48%和77%的反馈测量,而不会显着降低性能。

英文摘要:

The development of integrated sensing and communication (ISAC) systems has recently gained interest for its ability to offer a variety of services including resources sharing and new applications, for example, localization, tracking, and health care related. While the sensing capabilities are offered through many technologies, rending to their wide deployments and the high frequency spectrum they provide and high range resolution, its accessibility through the Wi-Fi networks IEEE 802.11ad and 802.11ay has been getting the interest of research and industry. Even though there is a dedicated standardization body, namely the 802.11bf task group, working on enhancing the Wi-Fi sensing performance, investigations are needed to evaluate the effectiveness of various sensing techniques. In this project, we, in addition to surveying related literature, we evaluate the sensing performance of the millimeter wave (mmWave) Wi-Fi systems by simulating a scenario of a human target using Matlab simulation tools. In this analysis, we processed channel estimation data using the short time Fourier transform (STFT). Furthermore, using a channel variation threshold method, we evaluated the performance while reducing feedback. Our findings indicate that using STFT window overlap can provide good tracking results, and that the reduction in feedback measurements using 0.05 and 0.1 threshold levels reduces feedback measurements by 48% and 77%, respectively, without significantly degrading performance.
