Radar-Enabled Ambient Backscatter Communications
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).

Multi-antenna Tag Ambient Backscatter System Based on Clustering Analysis
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

Performance Analysis of Ambient Backscatter NOMA Systems
This paper analyzed the performance of an ambient-backscatter-(AmBC)-assisted non-orthogonal multiple access (NOMA) system, where a backscatter device (BD) broadcasts its signal to numerous users. More specifically, the realistic assumptions of imperfect

Secret Key Generation Between Ambient Backscatter Devices
We analyze secret key generation between ambient backscatter devices where the channel between an ambient transmitter and the backscatter devices is used as a source of randomness.

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 ...

An Approximate BER Analysis for Ambient Backscatter Communication Systems With Tag Selection
Ambient backscatter is a new technology that uses ambient signals to enable communication between battery-free tags (or sensors) and readers. Previous studies on ambient backscatter focused on scenarios with only one tag.
