The research on Wi-Fi sensing has been thriving over the past decade but the process has
not been smooth. Three barriers always hamper the research: 1) unknown baseband design …

Indoor gesture recognition technology is concerned with making the machine accurately
recognize dynamic gestures within a certain range. Remarkably, most of this technology is …

This study proposes a sensing method using a millimeter-wave array radar and a depth
camera to measure pulse waves at multiple sites on the human body. Using a three …

In this paper, we propose a trajectory-driven three-dimensional (3D) non-stationary channel
model for millimeter wave (mm-Wave) single-input single-output (SISO) systems. The …

Wi-Fi channel state information (CSI) has been widely utilized in various motion sensing
applications such as motion detection, recognition, localization and tracking. Comparison …

Recent studies have found the mapping relationship between channel state information
used in commercial Wi-Fi devices and environmental changes in the indoor environment …

In this letter, a physical optics (PO)-based scattered field calculation method is introduced.
The proposed method divides the object into circular meshes. This technique exploited the …
