Radio shot: Through-the-wall human recognition
@article{Xu2016RadioST, title={Radio shot: Through-the-wall human recognition}, author={Qinyi Xu and Yan Chen and Beibei Wang and K. J. Ray Liu}, journal={2016 IEEE Global Conference on Signal and Information Processing (GlobalSIP)}, year={2016}, pages={1067-1071} }
In this work, we show the existence of human radio biometrics and present a human identification system that can discriminate individuals even through the walls in a non-line-of-sight condition. Using commodity WiFi devices, the proposed system captures the channel state information (CSI) and extracts human radio biometric information from WiFi signals using time-reversal (TR) technique. By leveraging the fact that broadband wireless CSI has significant number of multipaths, which can be…
