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 ...
