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 ...

Interference Analysis of Bi-static Backscatter Communication System: Two Backscatter Devices
2021 IEEE International Conference on RFID Technology and Applications (RFID-TA), 2021 Ambient backscatter communication (AmBC) systems utilize existing ambient radio frequency (RF) signals to establish an indirect communication link between a transmitter (TX) and a receiver (RX). Backscatter devices (BDs) modulate their useful information on the incoming ambient signal emitted by the TX, as such their range is usually a very short event
