Wi-Tracker: Monitoring Breathing Airflow with Acoustic Signalsaled airflow on the reflected sound waves to detect breathing. By analyzing the data collected from real sleep environments, we find that Power Spectral Density (PSD) of acoustic signals can be utilized to sense breathing procedures. Specifically, Wi-Tracker first adopts a Cumulative PSD method to e非实体 发表于 2025-3-30 13:53:52

Fusing Directional and Omnidirectional Wi-Fi Antennas for Accurate Indoor Localizationelation estimation, we model the localization problem with Dempster-Shafer (DS) theory and directional AP guidance to estimate the confidence values of AP signals adaptively. Furthermore, we remove the division in DS theory to avoid the paradox problem. We have implemented our algorithm and conducte集聚成团 发表于 2025-3-30 21:32:18
