Living-Body Ranging Method Using SISO Wi-Fi Radar

This paper proposes a human-body ranging method using SISO Wi-Fi radar. This method estimates target distance using Time-Of-Flight (TOF) calculated by Orthogonal Frequency Division Multiplexing (OFDM) signal. The simulation showed that the proposed method reduces the estimation error by 4.59 m at 75 percentile compared to the case without removing phase error.
