WiTrack+: Modeling and Compensating Through-Wall Doppler Frequency Shift Offsets for Non-Line-of-Sight Wi-Fi Tracking

Device-free human tracking using commodity Wi-Fi has garnered significant interest due to its potential for ubiquitous indoor sensing without the need for user instrumentation. However, achieving precise tracking in non-line-of-sight (NLoS) scenarios, particularly in through-wall environments, remains a challenging iss...
