CSI Phase Averaging for High-Sensitivity Wi-Fi Sensing in Low-Multipath Environments
arXiv:2606.07347v1 Announce Type: cross Abstract: This paper presents a low-complexity motion detection method for outdoor Wi-Fi sensing based on a model-driven approach. The method exploits the structural characteristics of the phase components in channel state information (CSI) for low-multipath propagation environments, which are generally considered disadvantageous for Wi-Fi sensing, to mitigate the phase offset errors originating from wireless devices. In addition, phase averaging...
