Covert Communication in Backscatter Radio

ICC 2019 - 2019 IEEE International Conference on Communications (ICC), 2019
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

Exploiting noncircularity in backscattering communications

2015 International Symposium on Wireless Communication Systems (ISWCS), 2015
In backscatter radio systems, a passive (i.e., battery-free) device (so-called tag) is able to transmit information by harvesting energy from a carrier transmitted by an access point or base station (so-called reader), thus enabling significant power savings compared to traditional wireless communication schemes.

Backscatter radio communication for wireless powered communication networks

2015 21st Asia-Pacific Conference on Communications (APCC), 2015
Backscatter radio communication has become a newly emerging technique for low-rate, low-power and large-scale wireless sensor networks. As this promising technology enables a long-range communication for sensors with low power in a distributed area, it is desirable to support wireless powered communication networks (WPCNs) that experience doubly near ...

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.

Multichannel radar backscatter communication and localization

2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014
This paper concerns the use of wideband RF backscatter from semi-passive RF tags for energy-efficient wireless telemetry. Using LFM (Linear Frequency Modulated) signals from a radar base station, we present a method for joint ranging and communications with a distributed set of sensor nodes. Backscatter signaling from each node results in modulation on

Backscatter communications with NOMA (Invited Paper)

2018 15th International Symposium on Wireless Communication Systems (ISWCS), 2018
In this paper, we study a multiple access monostatic backscatter communication (BackCom) system, where one reader talks to multiple backscatter nodes (BNs). We propose to use nonorthogonal multiple access (NOMA) to improve the efficiency of BackCom system.
