Turbocharging ambient backscatter communication

Proceedings of the 2014 ACM conference on SIGCOMM, 2014
Communication 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.

Perfect pulses for ambient backscatter communication

2017 IEEE International Conference on RFID (RFID), 2017
This paper explains how to construct perfect pulses - antipodal binary waveforms with extraordinary DC-nulling properties. Several methods for employing perfect pulses in digital modulation schemes, with particular emphasis on backscatter (and simply scatter) radio modulation, are demonstrated.

Defeating Jamming Attacks with Ambient Backscatter Communications

2020 International Conference on Computing, Networking and Communications (ICNC), 2020
While the existing anti-jamming solutions tend to “escape” the attacks by finding another communication channel or adapting, waiting until the attacks cease, this work proposes an unprecedented method to combat jammers by leveraging the jamming signals to transmit data based on the recent advances in ambient backscatter communication technology.

Ambient Backscatter Communication Systems With MFSK Modulation

IEEE Transactions on Wireless Communications, 2019
The ambient backscatter communication is a newly rising paradigm for the Internet-of-Things networks, which enables the connection of low-cost devices. This paper proposes a novel MFSK modulation for the Tag of ambient backscatter communications systems, and the corresponding detectors are designed depending on the capability of the Reader. In the case

Ph.D. Forum Abstract: Ambient Backscatter Communication

2016 15th ACM/IEEE International Conference on Information Processing in Sensor Networks (IPSN), 2016
Ambient backscatter communication, where energy and wireless carrier are extracted from existing radio signals, are very attractive to the Internet of Things. This technology is emerging as an enabler for battery-less sensor nodes that can operate unattended for extended periods of time.

Adaptive Ambient Backscatter Communication Systems With MRC

IEEE Transactions on Vehicular Technology, 2018
Ambient backscatter (AmBack) communication, also called “modulation in the air,” has drawn growing interest by both academia and industry recently. In this paper, we investigate and analyze an AmBack system, where the user is equipped with an AmBack circuit at the transmitter and maximum ratio combing at the receiver.
