Enabling Multicarrier Backscattering Communications
2020 IEEE MTT-S International Wireless Symposium (IWS), 2020We demonstrate for the first time that a multicarrier signal, and in particular an OFDM signal, can be generated by backscattering a single carrier incoming electromagnetic wave. This is achieved by utilizing a semi-passive IQ backscatter modulator involving two transistors with varying biasing in a Wilkinson power divider architecture that has ...

Radar-enabled backscatter communication
2022 56th Asilomar Conference on Signals, Systems, and Computers, 2022In this work, we propose to use the echoes generated by a radar as a carrier waveform to establish and sustain a communication link between an ambient backscatter transmitter (tag) and a destination node (reader): we refer to this novel architecture as radar-enabled backscatter communication.

Monostatic MIMO Backscatter Communications
IEEE Journal on Selected Areas in Communications, 2020Backscatter communications have two major antenna configurations: the bistatic configuration, in which the reader employs two different sets of antennas to transmit and receive, and the monostatic configuration, in which the reader employs one set of antennas for both transmitting and receiving.

Turbocharging ambient backscatter communication
Proceedings of the 2014 ACM conference on SIGCOMM, 2014Communication primitives such as coding and multiple antenna processing have provided significant benefits for traditional wireless systems. Existing designs, however, consume significant power and computational resources, and hence cannot be run on low complexity, power constrained backscatter devices.

Turboboosting Visible Light Backscatter Communication
Proceedings of the Annual conference of the ACM Special Interest Group on Data Communication on the applications, technologies, architectures, and protocols for computer communication, 2020Visible light backscatter communication (VLBC) presents an emerging low power IoT connectivity solution with spatial reuse and interference immunity advantages over RF-based (backscatter) technologies. State-of-the-art VLBC systems employ COTS LCD shutter as optical modulator, whose slow response fundamentally throttles its data rate to sub-Kbps, and ...

Optimization of FSO quantum backscatter communication
Applied Optics, 2019In this paper, the free-space optics (FSO) quantum backscatter communication (QBC), inspired by the quantum illumination concept, is described. In this method, the transmitter generates entangled photon pairs. The signal photon is transmitted in the direction of the modulated retro reflector (MRR) or the tag antenna, and the idler photon is moved to ...

An Overview on Backscatter Communications
Journal of Communications and Information Networks, 2019As a key low-power communication technique, backscatter communications exploits the reflected or backscattered signals to transmit data, where the backscattered signals can be the reflection of ambient radio frequency (RF) signals, the RF signals from the dedicated carrier emitter or the signal photons in the non-classical quantum entangled pairs, etc.
