Ambient Backscatter Communication Design over DCSK Signals
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 ...

Demo Abstract: Real-Time Ambient Backscatter Demonstration [PDF]
To lower power consumption and spectral congestion, it has been proposed to transmit digital informations by modulating the ambient electromagnetic waves emitted by different RF sources such as TV broadcast, Wifi. We have recently developed prototypes of backscatter tags and readers operating in real-time recycling DVB-T and 4G RF fields.
