Fig. 8From: Leveraging MIMO-OFDM radio signals for device-free occupancy inference: system design and experimentsROC results using the multi-frequency occupancy detector (that exploits spatial correlations), the multi-link occupancy detector (that uses frequency correlations), and the trivial detector. The measurements adopted for these plots are related to the double target scenario where the bodies move along the main LOS path (connecting TX and RX2)Back to article page
