Abstract(in English) | This study investigates a living-body positioning technique that integrates Time-of-flight (ToF) and Direction of Departure (DoD) utilizing real Wi-Fi stations. To realize a low-cost radar system well-suited for IoT-based applications, we assume a Multiple-Input-Single-Output (MISO) system, where the Wi-Fi station has multiple transmit antennas and only a single receive antenna available. Also, the Wi-Fi uses Orthogonal Frequency Division Multiplexing (OFDM) signals, offering Channel State Information (CSI) over the subcarriers. Our technique includes the CSI calibration, which is essential for the positioning application because the CSI has a phase error due to the clock difference between the transmitter and receiver, etc. A joint ToF-DoD detection technique is introduced to detect the target position, where the Doppler shifted component is retrieved by applying Fourier transformation to the observed CSI. The experimental results confirm that our Wi-Fi-based radar could successfully localize the target's position. |
