Boosting wifi sensing performance via CSI ratio

Résumé

The past few years have witnessed the great potential of exploiting channel state information (CSI) retrieved from commodity WiFi devices for contactless human sensing. However, a severe problem hindering practical WiFi sensing applications is that the obtained CSI data contains a large amount of noise, leading to short sensing range and low sensing accuracy. Aiming at solving the critical problem, in this article, we propose to employ a new base signal called CSI ratio to boost the WiFi sensing performance.
