Secrecy Wireless‐Powered Sensor Networks for Internet of Things

open access: yesWireless Communications and Mobile Computing, Volume 2020, Issue 1, 2020., 2020
This paper investigates a secure wireless‐powered sensor network (WPSN) with the aid of a cooperative jammer (CJ). A power station (PS) wirelessly charges for a user equipment (UE) and the CJ to securely transmit information to an access point (AP) in the presence of multiple eavesdroppers.

Evaluation of Maximum Range for Backscattering Communications Utilising Ambient FM radio signals [PDF]

open access: yes, 2022
The objective of this article is to evaluate the maximum range of ambient backscattering communications (AmBC). FM radio signals operating at 100 MHz are selected as the ambient signal due to their large communication ranges. The FM radio signals operate

An Efficient Ratio Detector for Ambient Backscatter Communication [PDF]

open access: yes, 2023
A challenge of ambient backscatter communication (AmBC) systems is signal recovery because the transmitted information bits are embedded in the ambient RF signals and these are unknown and uncontrollable.

Ambient backscatter communications over NOMA downlink channels [PDF]

open access: yes, 2020
In this paper, we investigate the performance of commensal ambient back-scatter communications (AmBC) that ride on a non-orthogonal multiple access (NOMA) downlink transmission, in which a backscatter device (BD) splits part of its received signals from ...

Design of a New CIM-DCSK-Based Ambient Backscatter Communication System

open access: yes, 2023
To improve the data rate in differential chaos shift keying (DCSK) based ambient backscatter communication (AmBC) system, we propose a new AmBC system based on code index modulation (CIM), referred to as CIM-DCSK-AmBC system.
