Adaptive Transmission Repetition and Combining in Bistatic WiFi Backscatter Communications
IEEE Access, 2020 Extracting data bits from bistatic-backscattered WiFi signals by threshold-based decoding is challenging due to severe fluctuation of OFDM signals. We propose adaptive transmission repetition to combat this problem.

Defeating Eavesdroppers with Ambient Backscatter Communications
2023 IEEE Wireless Communications and Networking Conference (WCNC), 2023 Unlike conventional anti-eavesdropping methods that always require additional energy or computing resources (e.g., in friendly jamming and cryptography-based solutions), this work proposes a novel anti-eavesdropping solution that comes with mostly no extra power nor computing resource requirement.

Spectro-Temporal Combining in Bistate WiFi Backscatter Communication With Frequency Shift
IEEE Access, 2021 In WiFi backscatter communication, the frequency shift technique allows a backscattered signal to appear not in the frequency channel of the carrier signal but in adjacent ones, thus avoiding noisy OFDM-based carrier signals and increasing the ...
