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.

LoS sensing-based superimposed CSI feedback for UAV-Assisted mmWave systems
在无人机辅助毫米波系统中,信道状态信息(CSI)反馈对于调制方案的选择、资源管理、波束形成等至关重要。然而,传统的CSI反馈方法会导致UAV发射机的显著反馈开销和能量消耗,从而缩短系统的运行时间。为了解决这些问题,受叠加反馈和通感一体化(ISAC)的启发,提出了一种基于视距(LoS)传感的叠加CSI反馈方案。具体地,在UAV发射器侧,地面到UAV(G2 U)CSI叠加在UAV到地面(U2 G)数据上以反馈到地面基站(gBS)。在gBS处,专用LoS感测网络(LoSSenNet)被设计为在LoS和NLoS场景中感测U2 G CSI。利用LoS-SenNet的感测结果,从初始特征提取中确定的G2 U CSI将用作先验信息以指导后续操作。具体地,对于NLoS中的G2 U CSI,开发CSI恢复网络(CSI-RecNet)和叠加干扰消除以恢复G2 U CSI和U2 G数据。对于LoS场景,在CSI-RecNet和叠加干扰消除块之前嵌入专用LoS辅助网络(LoS-AidNet),以突出G2 U CSI的特征。仿真结果表明,与其他叠加CSI反馈方法相比,该反馈方案有效地提高了G2 U CSI和U2 G数据的恢复精度。此外,对参数变化,所提出的反馈方案显示其鲁棒性。
