Multi-antenna Tag Ambient Backscatter System Based on Clustering Analysis
Taiyuan Ligong Daxue xuebao, 2021 Ambient backscatter technology can effectively solve the energy problems of communication and battery-free equipment. The ambient backscatter communication system uses a single antenna tag for communication and carries out signal detection at the cost of

Radar-Enabled Ambient Backscatter Communications
IEEE Transactions on Wireless Communications, 2023 In this work, we exploit the radar clutter (i.e., the ensemble of echoes generated by the terrain and/or the surrounding objects in response to the signal emitted by a radar transmitter) as a carrier signal to enable an ambient backscatter communication from a source (tag) to a destination (reader).

Ambient Backscatter Communication Design over DCSK Signals
International Journal of Bifurcation and Chaos, 2021 In this paper, a novel ambient backscatter communication system is proposed, in which Differential Chaos Shift Keying (DCSK) modulation signals are adopted as ambient RF source. In order to cancel out the strong direct-link interference as well as reduce the noise impact, a joint design of modulation waveform and signal detector is proposed, and ...

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.
