In-body backscatter communication and localization [PDF]
Backscatter requires zero transmission power, making it a compelling technology for in-body communication and localization. It can significantly reduce the battery requirements (and hence the size) of micro-implants and smart capsules, and enable them to be located on-the-move inside the body.

Quantum Backscatter Communication: A New Paradigm [PDF]
In this paper, we propose a novel quantum backscatter communications (QBC) protocol, inspired by the quantum illumination (QI) concept. In the QBC paradigm, the transmitter generates entangled photon pair. The signal photon is transmitted and the idler photon is kept at the receiver.

Covert Communication in Backscatter Radio
Covert communication in backscatter radio systems is considered, where the transmitter controls its transmit power to keep the transponder's response hidden, while a warden tries to detect this covert communication. To achieve covertness, we propose a non-conventional transmission scheme where the transmitter emits noise-like signal with transmit power

Backscatter Communications [PDF]
This paper addresses backscatter communications as a new paradigm for Internet of Things (IoT) sensor wireless solutions. The paper clearly presents the history background of the technology and then makes a summary of the more recent developments form several groups around the world, with emphasis in US and Europe groups.

NOMA Enhanced Backscatter Communication for Green IoT Networks [PDF]
Backscatter communication has recently emerged as a promising technology to enable passive sensing-based Internet-of-things (IoT) applications. In a backscatter communication network, uplink transmissions of multiple nodes are usually multiplexed in time-

Quantum-Enhanced Microwave Backscattering Communications [PDF]
The recent advances in the field of microwave superconducting circuits open the way for a multitude of engineering applications that revolutionize the field of classical communications. To exploit this new technology, we propose a novel microwave quantum-enhanced backscattering system based on the laws of quantum physics.

The influence of magnetospheric substorms on SuperDARN radar backscatter [PDF]
The SuperDARN ionospheric radar network is a leading tool for investigating the near-Earth space environment. However, reductions in ionospheric backscatter have been reported during magnetospheric substorms.

Multiantenna Quantum Backscatter Communications [PDF]
Quantum illumination (QI) is a revolutionary photonic quantum sensing paradigm that enhances the sensitivity of photodetection in noisy and lossy environments. The QI concept has been recently used to propose a quantum backscatter communication (QBC), with the aim of increasing the receiver sensitivity beyond the limits of its classical counterpart ...

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).
